Miguel García-Garibay, dean of the UCLA Division of Physical Sciences and professor of chemistry and biochemistry, has been elected a 2019 fellow of the American Chemical Society, the ACS announced.

García-Garibay is a pioneer in research on molecular motion in crystals, molecular machines and green chemistry.

He has earned worldwide recognition in the fields of organic photochemistry, solid-state organic chemistry and physical organic chemistry. García-Garibay studies the interaction of light and molecules in crystals. Light can have enough energy to break and make bonds in molecules, and his research team has shown that crystals offer an opportunity to control the outcome of these chemical reactions. He is interested in the basic science of molecules in crystals.

His research has applications for green chemistry that may lead to the production of specialty chemicals that would be very difficult to produce by traditional methods due to their complex structures, as well as applications for molecular electronics and miniaturized devices. His research group has made advances in the field of artificial molecular machines and amphidynamic crystals, a term García-Garibay invented, referring to crystals built with molecules that have a combination of static and mobile components. His research is funded by the National Science Foundation, among other funding sources.

“I can get a precise picture of the molecules in the crystals, the precise arrangement of atoms, with almost no uncertainty,” García-Garibay said. “This provides a large level of control, which enables us to learn the different principles governing molecular functions at the nanoscale.”

He has won many honors for his research, including selection as a fellow of the American Association for the Advancement of Science, as well as numerous honors from the National Science Foundation and the American Chemical Society. He is a member of the California NanoSystems Institute and the Society for Advancement of Chicanos/Hispanics and Native Americans in Science, among other scholarly organizations.

ACS fellows are nominated by their peers and selected for their outstanding accomplishments in scientific research, education and public service. The 2019 fellows will be honored at a ceremony during the ACS national meeting in San Diego on Aug. 26.

Professor Richard Kaner and researcher Maher El-Kady have designed a series of remarkable devices. Their newest one creates electricity from falling snow. The first of its kind, this device is inexpensive, small, thin and flexible like a sheet of plastic.

“The device can work in remote areas because it provides its own power and does not need batteries,” said Kaner, the senior author who holds the Dr. Myung Ki Hong Endowed Chair in Materials Innovation.“It’s a very clever device — a weather station that can tell you how much snow is falling, the direction the snow is falling and the direction and speed of the wind.”

The researchers call it a snow-based triboelectric nanogenerator, or snow TENG. Findings about the device are published in the journal Nano Energy.

The device generates charge through static electricity. Static electricity occurs when you rub fur and a piece of nylon together and create a spark, or when you rub your feet on a carpet and touch a doorknob.

“Static electricity occurs from the interaction of one material that captures electrons and another that gives up electrons,” said Kaner, who is also a distinguished professor of chemistry and biochemistry, and of materials science and engineering, and a member of the California NanoSystems Institute at UCLA. “You separate the charges and create electricity out of essentially nothing.”

Snow is positively charged and gives up electrons. Silicone — a synthetic rubber-like material that is composed of silicon atoms and oxygen atoms, combined with carbon, hydrogen and other elements — is negatively charged. When falling snow contacts the surface of silicone, that produces a charge that the device captures, creating electricity.

“Snow is already charged, so we thought, why not bring another material with the opposite charge and extract the charge to create electricity?” said El-Kady, assistant researcher of chemistry and biochemistry.

“After testing a large number of materials including aluminum foils and Teflon, we found that silicone produces more charge than any other material,” he said.

Approximately 30 percent of the Earth’s surface is covered by snow each winter, El-Kady noted, during which time solar panels often fail to operate. The accumulation of snow reduces the amount of sunlight that reaches the solar array, limiting their power output and rendering them less effective. The new device could be integrated into solar panels to provide a continuous power supply when it snows.

The device can be used for monitoring winter sports, such as skiing, to more precisely assess and improve an athlete’s performance when running, walking or jumping, Kaner said. It could usher in a new generation of self-powered wearable devices for tracking athletes and their performances. It can also send signals, indicating whether a person is moving.

The research team used 3-D printing to design the device, which has a layer of silicone and an electrode to capture the charge. The team believes the device could be produced at low cost given “the ease of fabrication and the availability of silicone,” Kaner said.

New device can create and store energy

Kaner, El-Kady and colleagues designed a device in 2017 that can use solar energy to inexpensively and efficiently create and store energy, which could be used to power electronic devices, and to create hydrogen fuel for eco-friendly cars.

The device could make hydrogen cars affordable for many more consumers because it produces hydrogen using nickel, iron and cobalt — elements that are much more abundant and less expensive than the platinum and other precious metals that are currently used to produce hydrogen fuel.

“Hydrogen is a great fuel for vehicles: It is the cleanest fuel known, it’s cheap and it puts no pollutants into the air — just water,” Kaner said. “And this could dramatically lower the cost of hydrogen cars.”

The technology could be part of a solution for large cities that need ways to store surplus electricity from their electrical grids. “If you could convert electricity to hydrogen, you could store it indefinitely,” Kaner said.

Kaner is among the world’s most influential and highly cited scientific researchers. He has also been selected as the recipient of the  American Institute of Chemists 2019 Chemical Pioneer Award, which honors chemists and chemical engineers who have made outstanding contributions that advance the science of chemistry or greatly impact the chemical profession.

Co-authors on the snow TENG work include Abdelsalam Ahmed, who conducted the research while completing his Ph.D. at the University of Toronto, and Islam Hassan and Ravi Selvaganapathy at Canada’s McMaster University, as well as James Rusling, who is the Paul Krenicki professor of chemistry at the University of Connecticut, and his research team.

More devices designed to solve pressing problems

Last year, Kaner and El-Kady published research on their design of the first fire-retardant, self-extinguishing motion sensor and power generator, which could be embedded in shoes or clothing worn by firefighters and others who work in harsh environments.

Kaner’s lab produced a separation membrane that separates oil from water and cleans up the debris left by oil fracking. The separation membrane is currently in more than 100 oil installations worldwide. Kaner conducted this work with Eric Hoek, professor of civil and environmental engineering.

Laure Murat roils the #MeToo debate in France

In a recent book, Director of the UCLA Center for European and Russian Studies Laure Murat argues that #MeToo is the first serious challenge to patriarchy in modern times, and dismisses the current discussion of #MeToo in France as a polemical misdirection. Instead, she calls for a genuine debate on the issues of sexual harassment and assault that engages French young people, men and women, philosophers and intellectuals.

Born and raised in Paris, Murat is a well-known independent author and intellectual in France, but has lived and worked in the United States for the last 12 years, where she is a UCLA professor of French and Francophone studies. As a result, she has a unique perspective on #MeToo and its divergent receptions in the United States and France.

Focusing on the issues

Her book, Une révolution sexuelle? Réflexions sur l’après-Weinstein [A Sexual Revolution? Reflections on the Weinstein Aftermath], has fueled an ongoing rancorous debate about #MeToo in France, with Muratappearing on leading French television and radio shows to discuss the book, while also being interviewed by multiple French newspapers and online publications.

To give American readers an idea of the nature of the debate in France, some 100 well-known French women — including actress Catherine Deneuve — published an open letter in the left-leaning Le Monde that rejected the #MeToo movement and defended men’s “freedom to pester.”

The month before Une révolution sexuelle? was released, French journalist Eugénie Bastié of the conservative Le Figaro newspaper published Le Porc Émissaire: Terreur ou contre-révolution? [Blame the Pig: Terror or Counter-Revolution?], which decries the #MeToo movement for its supposed encouragement of victimization. Rightly or wrongly, one sentence in Bastié’s book has become emblematic of the French critique of #MeToo: “Une main aux fesses n’a jamais tué personne, contrairement aux bonnes intentions qui pavent l’enfer des utopies [A hand on someone’s ass never killed anyone, contrary to the good intentions that pave utopian hells].”

In fact, the views of Murat and Bastié were compared by Elisabeth Philippe of Bibliobs in an article titled Où vont les femmes après #MeToo? Le match Eugénie Bastié – Laure Murat [Where are women headed after #MeToo? The Eugénie Bastié – Laure Murat Competition].

Renewed dialogue for the young generation

Murat argues that polemics are preventing a real debate on the issues of sexual harassment and assault in France, as made clear in a translation of En France, #MeToo est réduit à une caricature pour éviter le débat [In France, #MeToo is being reduced to a caricature to avoid debate], a Mediapart.fr interview conducted by Marine Turchi:

Today, one could say that France is the country of the non-debate. I am struck by the intellectual void and the deliberate desire of the media to extinguish the issues by means of false polemics.

Instead of posing good questions, they rekindle the war of the sexes and clichés of “hysterical feminists” and “poor men,” they invoke masculinity and the freedom to pester, they feel sorry for men who sexually harass women on the subway, they discuss the excesses and possible ambiguities of #MeToo while they haven’t begun to discuss the heart of the problem. They oppose X and Y, right and left, for and against. …

Far from reanimating the war of the sexes, the #MeToo movement is, on the contrary, an exciting opportunity to understand and resolve the gulf between men and women, the gaps in consent, the sufferings of misunderstood sexuality, the logic of domination and abuse of power that poison personal and professional relationships. It’s the promise of renewed dialogue for the young generation. I really like the proposal of Gloria Steinem: eroticize equality (in other words, not violence and oppression).

The #MeToo debate is far from over in either the United States or France. Murat’s book offers new perspectives as the conversation continues.

Professor’s latest book examines the history of cities

The only thing a person really needs to be an archaeologist is a good sense of observation, UCLA professor of anthropology Monica Smith proclaims in her most recent book, “Cities: The First 6,000 Years.”

Advanced degrees and research experience are useful of course, but successful fieldwork is rooted in “noticing,” she said.

Archaeologists are always looking down noticing traces of what’s been left behind, and the stories detritus can tell, she said. These days at UCLA that might mean traces of glitter bombs launched by graduates during the last several weeks.

“We walk along and there’s all this glitter on the ground, and even though it gets cleaned away, you can never get it all so then you start to see little traces of glitter everywhere, because people are tracking it on their shoes all around campus,” Smith said. “We’re not only walking through an archaeological site, we’re making one.”

Smith is amused at the thought of future archaeologists encountering and interpreting the meaning behind those trace elements of shimmer in the dust around this particular area in one of Earth’s largest cities.

In vivid style, Smith’s latest book examines ways in which human civilization has organized itself into city life during the last 6,000 years, a relatively short time span in the grand scheme of human existence. Today, more than half of the world’s population resides in cities, and that number will continue to grow. But that wasn’t always so.

In “Cities,” Smith tracks the ways metropolitan hubs in different parts of the world emerged unrelated to one another, but in eerily similar forms, revealing the inherent similarities of humans’ needs regardless of what part of the world their civilization evolved.

“I started asking myself, ‘Why do these places all look the same even though they’re different times, different areas, different cultures and different languages?’” she said. “What is it about our human cognitive capacity that leads us to have the same form over and over and over again?”

She imagines how the first Spanish warriors to arrive in Cuzco in Peru, or Tenochtitlan in present day Mexico City, encountered the layout of ancient Inca and A

ztec cities, with shops and open squares and marketplaces resembling what they would see at home — despite the cultures never having had contact before.

“The similarities suggest that humans developed cities because it was the only way for a large number of people to live together in a single place where they could all get something new they wanted, whether that was a job, entertainment, medical care or education,” Smith said.

For the purposes of her analysis, Smith defines a city as a place with a dense population of multiple ethnicities; a diverse economy with an abundant variety of readily available goods; buildings and spaces of religion or ritual; a vertical building landscape that encompasses residential homes, courts, schools and government offices; formal entertainment venues; open grounds and multipurpose spaces; broad avenues and thoroughfares for movement.

Before cities, the human population was scattered across larger agrarian swaths, with families having everything they needed to survive in their own homes. People would come together for trading festivals or sacred ceremonies. These most likely began to last longer and longer, Smith said, creating a permanent collective settlement around places conducive to providing food, water, shelter and entertainment. Humans essentially took the bold step of living away from their immediate food supply to live in cities among larger groups of other humans.

Takeout food vendors have been a staple of cities stretching about as far back as you can get, with evidence of takeout food in ancient cities like Pompeii and Angkor, Smith notes in her book.

And cities allowed for the evolution of all kinds of new jobs and enterprises — bookkeeping, the service industry and managers — constituting a newly emergent middle class that found new opportunities to thrive in dense populations.

Some aspects of city life accelerated long-standing tendencies. Humans are a unique species in the animal kingdom due to our deep dependence on objects, a fact that aids archeologists in their work of noticing. Ancient cities also struggled with some of the same things we do in modern times — trash for example, Smith said.

“We think of ourselves as bad modern people because we have all this trash,” Smith said. “But everyone everywhere has trash. Ancient cities are full of trash. Modern cities are full of trash because people want more stuff.”

Archaeologists are obsessed with trash, Smith said. They learn much and encounter new questions from what was considered disposable to our ancestors.

Smith’s book also offers a descriptive window into day-to-day life on an archaeological dig, sharing challenges and the excitement of new technologies that help identify potential dig sites. People working to excavate subway tunnels and building foundations in modern Athens, Rome, Mexico City, Istanbul, Paris and other places are constantly finding new evidence of these metropolises’ earliest incarnations.

Much like current generations of young adults and children who cannot imagine a world without the internet, cities are here to stay, Smith said.

“From this point forward, there is no way that humans can live without urbanism, there is no ‘going back to the land,’” she said. “We can take a sort of comfort in the fact that the challenges we face like infrastructure, transportation, water sourcing, pollution and trash have essentially been a part of city life from the very beginning.”

Smith said one of the goals of her writing is to inspire people to think of cities as dynamic and adaptable.

“We can work to make cities not only more efficient, but more equitable, in the sense of social justice and greater opportunities for larger numbers of people, along with greater diversity,” she said. “Cities are not just inherited configurations, but are places with potential for growing into the better societies that we wish for ourselves and others.”

Results of UCLA-led study contradict a long-held classical theory

Everyday transitions from one state of matter to another — such as freezing, melting or evaporation — start with a process called “nucleation,” in which tiny clusters of atoms or molecules (called “nuclei”) begin to coalesce. Nucleation plays a critical role in circumstances as diverse as the formation of clouds and the onset of neurodegenerative disease.

A UCLA-led team has gained a never-before-seen view of nucleation — capturing how the atoms rearrange at 4D atomic resolution (that is, in three dimensions of space and across time). The findings, published in the journal Nature, differ from predictions based on the classical theory of nucleation that has long appeared in textbooks.

“This is truly a groundbreaking experiment — we not only locate and identify individual atoms with high precision, but also monitor their motion in 4D for the first time,” said senior author Jianwei “John” Miao, a UCLA professor of physics and astronomy, who is the deputy director of the STROBE National Science Foundation Science and Technology Center and a member of the California NanoSystems Institute at UCLA.

Research by the team, which includes collaborators from Lawrence Berkeley National Laboratory, University of Colorado at Boulder, University of Buffalo and the University of Nevada, Reno, builds upon a powerful imaging techniquepreviously developed by Miao’s research group. That method, called “atomic electron tomography,” uses a state-of-the-art electron microscope located at Berkeley Lab’s Molecular Foundry, which images a sample using electrons. The sample is rotated, and in much the same way a CAT scan generates a three-dimensional X-ray of the human body, atomic electron tomography creates stunning 3D images of atoms within a material.

Miao and his colleagues examined an iron-platinum alloy formed into nanoparticles so small that it takes more than 10,000 laid side by side to span the width of a human hair. To investigate nucleation, the scientists heated the nanoparticles to 520 degrees Celsius, or 968 degrees Fahrenheit, and took images after 9 minutes, 16 minutes and 26 minutes. At that temperature, the alloy undergoes a transition between two different solid phases.

Although the alloy looks the same to the naked eye in both phases, closer inspection shows that the 3D atomic arrangements are different from one another. After heating, the structure changes from a jumbled chemical state to a more ordered one, with alternating layers of iron and platinum atoms. The change in the alloy can be compared to solving a Rubik’s Cube — the jumbled phase has all the colors randomly mixed, while the ordered phase has all the colors aligned.

In a painstaking process led by co-first authors and UCLA postdoctoral scholars Jihan Zhou and Yongsoo Yang, the team tracked the same 33 nuclei — some as small as 13 atoms — within one nanoparticle.

“People think it’s difficult to find a needle in a haystack,” Miao said. “How difficult would it be to find the same atom in more than a trillion atoms at three different times?”

The results were surprising, as they contradict the classical theory of nucleation. That theory holds that nuclei are perfectly round. In the study, by contrast, nuclei formed irregular shapes. The theory also suggests that nuclei have a sharp boundary. Instead, the researchers observed that each nucleus contained a core of atoms that had changed to the new, ordered phase, but that the arrangement became more and more jumbled closer to the surface of the nucleus.

Classical nucleation theory also states that once a nucleus reaches a specific size, it only grows larger from there. But the process seems to be far more complicated than that: In addition to growing, nuclei in the study shrunk, divided and merged; some dissolved completely.

“Nucleation is basically an unsolved problem in many fields,” said co-author Peter Ercius, a staff scientist at the Molecular Foundry, a nanoscience facility that offers users leading-edge instrumentation and expertise for collaborative research. “Once you can image something, you can start to think about how to control it.”

The findings offer direct evidence that classical nucleation theory does not accurately describe phenomena at the atomic level. The discoveries about nucleation may influence research in a wide range of areas, including physics, chemistry, materials science, environmental science and neuroscience.

“By capturing atomic motion over time, this study opens new avenues for studying a broad range of material, chemical and biological phenomena,” said National Science Foundation program officer Charles Ying, who oversees funding for the STROBE center. “This transformative result required groundbreaking advances in experimentation, data analysis and modeling, an outcome that demanded the broad expertise of the center’s researchers and their collaborators.”

Other authors were Yao Yang, Dennis Kim, Andrew Yuan and Xuezeng Tian, all of UCLA; Colin Ophus and Andreas Schmid of Berkeley Lab; Fan Sun and Hao Zeng of the University at Buffalo in New York; Michael Nathanson and Hendrik Heinz of the University of Colorado at Boulder; and Qi An of the University of Nevada, Reno.

The research was primarily supported by the STROBE National Science Foundation Science and Technology Center, and also supported by the U.S. Department of Energy.

Babies Know the Difference between the Laughter of Friends and Strangers

Five-month-olds may use chuckles to identify information about social interactions

Most people can share a laugh with a total stranger. But there are subtle—and detectable—differences in our guffaws with friends.

Greg Bryant, a cognitive scientist at the University of California, Los Angeles, and his colleagues previously found that adults from 24 societies around the world can distinguish simultaneous “co-laughter” between friends from that between strangers. The findings suggested that this ability may be universally used to help read social interactions. So the researchers wondered: Can babies distinguish such laughter, too?

Bryant and his fellow researcher Athena Vouloumanos, a developmental psychologist at New York University, played recordings of co-laughter between pairs of either friends or strangers to 24 five-month-old infants in New York City. The babies listened longer to the laughs shared between buddies—suggesting they could tell the two types apart, according to a study published in March in Scientific Reports.

The researchers then showed the babies short videos of two people acting either like friends or strangers and paired those with the audio recordings. The babies stared for longer at clips paired with a mismatched recording—for example, if they saw friends interacting but heard strangers laughing.

“There’s something about co-laughter that is giving information to even a five-month-old about the social relationship between the individuals,” Bryant says. Exactly what components of laughter the infants are detecting remains to be seen, but prior work by Bryant’s team provides hints. Laughs between friends tend to include greater fluctuations in pitch and intensity, for example.

Such characteristics also distinguish spontaneous laughs from fake ones. Many scientists think unprompted laughter most likely evolved from play vocalizations, which are also produced by nonhuman primates, rodents and other mammals. Fake laughter probably emerged later in humans, along with the ability to produce a wide range of speech sounds. The researchers suggest that we may be sensitive to spontaneous laughter during development because of its long evolutionary history.

“It’s really cool to see how early infants are distinguishing between different forms of laughter,” says Adrienne Wood, a psychologist at the University of Virginia, who was not involved in the study. “Almost every waking moment is a social interaction for [babies], so it makes sense that they are becoming very attuned to their social worlds.”

UCLA’s Andrea Ghez with her sons at Oxford University.

Andrea Ghez, distinguished professor of physics and astronomy and director of UCLA’s Galactic Center Group, was awarded an honorary degree today from Oxford University during its annual Encaenia ceremony.

Ghez demonstrated the existence of a supermassive black hole at the center of our galaxy, with a mass 4 million times that of our sun. Her work provided the best evidence yet that these exotic objects really do exist, providing an opportunity to study the fundamental laws of physics in the extreme environment near a black hole, and learn what role this black hole has played in the formation and evolution of our galaxy.

She joins an eclectic group including cellist Yo-Yo Ma, Nobel laureate Daniel Kahneman, and UC Berkeley professor Jennifer Doudna, who developed the CRISPR-Cas9 technology for gene editing.

Ghez, who is the Lauren B. Leichtman & Arthur E. Levine Chair in Astrophysics, earned her bachelor’s degree in physics from MIT in 1987 and her doctorate from Caltech in 1992, and has been on the faculty at UCLA since 1994.

Chancellor’s Award for Community-Engaged Research to develop courses that bring research to L.A. community organizations

With the launch of the inaugural Chancellor’s Award for Community-Engaged Research, both undergraduate students and faculty have new opportunities to pursue research that impacts not just academia, but also local communities of Los Angeles.

The Chancellor’s Award for Community-Engaged Research comes from the UCLA Center for Community Learning and the Chancellor’s Office and has awarded six faculty members each a $10,000 research grant to develop a new undergraduate research course. In each course, students will carry out research activities in partnership with local community organizations. The course will advance their professor’s research goals and also benefit the communities served by each organization.

Over the next academic year, the six faculty will participate in a workshop on best practices for teaching undergraduate community-engaged research and attend quarterly meetings to advance their course design. By the end of spring 2020, each faculty will have a new course syllabus, ready to be offered to undergraduates in 2020-21 or 2021-22.

Shalom Staub, director of the Center for Community Learning, said the research reflects some of the most critical issues affecting people in and around UCLA.

“The range of issues includes representation of minority communities, health disparities, education disparities, environmental justice – that’s a catalogue of the big issues facing Los Angeles and southern California communities,” he said.

Maylei Blackwell, associate professor of Chicana and Chicano Studies, will develop a course called “The Latin American Indigenous Diaspora in Los Angeles: Mapping Place through Community Archives and Oral Histories.” Students will work with Zapotec and Mayan community organizations in Los Angeles to conduct interviews with community leaders and archive historical records such as community newspapers and home videos.

“I thought this course would be a perfect opportunity for community engagement: how do we produce those histories, how do we support those communities in documenting their own history, and [how do we] let the communities control how the process happens?” Blackwell said.

Chancellor Gene Block said the benefits of the Chancellor’s Award for Community-Engaged Research are threefold.

“Community-engaged research creates outstanding learning opportunities for undergraduate students, advances the research of our faculty, and benefits our community,” Block said. “The Community-Engaged Research Scholars will deepen UCLA’s commitment to public service by creating more opportunities for students and faculty to pursue research that has a positive impact on our world.”

Meredith Phillips, associate professor of public policy and sociology, is developing a course titled “Making Data Useful for Educational Improvement.” Students will analyze student and staff survey data from elementary, middle, and high schools, and present those data to school and district staff to help inform school improvement efforts.

The idea for the Chancellor’s Award for Community-Engaged Research is “brilliant,” Phillips said.

“This award recognizes faculty for their community-engaged research efforts and at the same time creates a new set of community-engaged course offerings for undergraduates,” she said. “This first set of courses is just the beginning of what I expect will eventually be an extensive suite of courses, across a wide range of disciplines, that will connect UCLA students’ research training with the needs of our local community.”

In the very first day of his “Introduction to Marine Science” class, Paul Barber tells his students an amusing story about himself. It has to do with how a guy from Tucson, Arizona — in the middle of the Sonoran Desert — became a marine scientist.

Full of twists and turns, the story is also an inspiring one. It tells how Barber, a professor of ecology and evolutionary biology, grew up in a low-income family and attended an inner-city middle school where he once had a .45 caliber handgun pointed at his head.

“It was in the middle of class, and my teacher never even noticed,” Barber said.

Military recruiters, not college recruiters, came to Barber’s high school. But he studied hard and won a full-ride Flinn Foundation scholarship, which enabled him to attend the University of Arizona. His interest in terrestrial evolutionary genetics was sparked by classes in animal behavior and herpetology, which is the study of amphibians and reptiles. Yet it took a roundabout series of adventures while he was a graduate student at UC Berkeley — involving frogs, mongooses, hyenas, clownfish and mantis shrimp — to bring him to his current position at UCLA.

“The punchline I tell the students is that, here I am, teaching a marine science course, and I’ve never taken a marine science course in my entire life,” Barber said. “And the fact that they are in that class means that they are so much further ahead of where I was at this point in their studies. If I can do this, never having done a marine science course in my life, then they are well-positioned to succeed.”

It’s this humility that endears Barber to both his students and his peers, several of whom endorsed him for the 2019 Gold Shield Faculty Prize — a $30,000 award presented annually by Gold Shield, Alumnae of UCLA, to an exceptional mid-career full professor with a distinguished record of undergraduate teaching, research and university service.

Almost since his arrival at UCLA in 2008, Barber has served as the director of the Program for Excellence in Education and Research in the Sciences, known as PEERS, a two-year program for outstanding students who wish to pursue careers in the life or physical sciences. In particular, PEERS emphasizes the recruitment and retention of students from groups traditionally underrepresented in science. Studies of the program show that its students are nearly twice as likely to complete a science degree and earn better grades than similar students not in PEERS.

Equally impressive is a summer program Barber founded 16 years ago, The Diversity Project, that he now runs with UCLA colleague Peggy Fong, also a professor of ecology and evolutionary biology. The Diversity Project is designed to increase diversity in marine science — a field with a very low percentage of traditionally underrepresented minorities — and provides undergraduate students with opportunities to conduct research outside the United States, ultimately inspiring them to continue in marine science.

“We go to amazing places, like Indonesia, that have the most diverse and spectacular coral reefs on the planet,” Barber said. Nearly 70% of program alumni go on to graduate school. Among the schools from which they have earned degrees: Harvard, Stanford, UC Santa Cruz, the Scripps Institution of Oceanography and UCLA.

“Dr. Barber is a strong mentor, and I know for a fact that I am a stronger scientist because of his support,” said Camille Gaynus, an alumna of The Diversity Project. “His mentorship is embedded in me, and I strive to pass on the same sentiments to the undergrads and high school students I currently mentor. Because of Dr. Barber, I know I will become a professor and continue to provide opportunities to young scientists, particularly Black females like myself.”

UCLA microbiologist Patricia J. Johnson elected to National Academy of Sciences

Patricia J. Johnson, UCLA professor of microbiology, immunology and molecular genetics, was elected to the National Academy of Sciences in recognition of her “distinguished and continuing achievements in original research.”

Membership in the academy is one of the highest honors that a U.S. scientist can receive. Its members have included Albert Einstein, Thomas Edison, Orville Wright and Alexander Graham Bell. The academy today announced the election of 100 new members and 25 foreign associates.

“I am very honored to be include among the ranks of such distinguished scientists,” said Johnson, who has appointments in the David Geffen School of Medicine at UCLA and the division of life sciences in the UCLA College.

Research in Johnson’s laboratory focuses on the molecular and cellular biology of a single cellular parasite called Trichomonas vaginalis. This microbe is responsible for the most prevalent, non-viral, sexually transmitted infection worldwide and is the most common parasite found in the U.S. population. An estimated 275 million people worldwide have the parasite, including approximately 3.7 million in the United States. In 2014, the Centers for Disease Control and Prevention identified trichomoniasis, the infection caused by T. vaginalis, as one of the “neglected parasitic infections in the United States.”

Johnson said that beyond its medical importance, T. vaginalis is a fascinating organism for conducting research on the evolution of biological processes present in all eukaryotes, from microbes to humans. The parasite’s atypical properties offer possible chemotherapeutic targets and vaccine candidates, she said.

Her laboratory focuses on several aspects of trichomonad biology, including its evolution, regulation of gene expression, drug resistance, genomics and biological processes vital for human infection.

“Our interdisciplinary research program merges several specialties, including structural and cell biology, biochemistry, genomics, proteomics, bioinformatics, evolution and medical sciences,” she said. “In recent years, we have narrowed our focus to defining and explaining critical pathogenic mechanisms that allow T. vaginalis to establish and maintain an infection. These studies include identifying critical parasite cell surface molecules and secreted vesicles, as well as defining human immune responses to parasitic infection. We have also investigated a possible link between infection with T. vaginalis and prostate cancer.”

The National Academy of Sciences was established in 1863 by a congressional act of incorporation signed by Abraham Lincoln that calls on the academy to act as an official adviser to the federal government, upon request, in any matter of science or technology. The academy is a private organization of scientists and engineers dedicated to the furtherance of science and its use for the general welfare.
