Chair's Message

Howard Hu, MD, MPH, ScD, Flora L. Thornton Chair and Professor of Population and Public Health, Department of Population and Public Health Sciences, Keck School of Medicine of USC

There is so much to be proud of as we marshal our thoughts about our department’s achievements in our second annual report. As touched on within, once again, we have ranked #2 in NIH funding amongst our peers, demonstrating an endorsement of the quality as well as the scale of the research we are leading in a multitude of areas. Our faculty continue to be recognized as leaders in their fields, with, for example, Professor Fejzo being named as one of Time Magazine’s 'Women of the Year' for her ground-breaking work deciphering the causes of hyperemesis gravidarum – a condition that plagues pregnant women world-wide. Our researchers are making key discoveries on the threats to human health from chemicals in e-cigarettes and environmental contaminants such as PFAS. We continue to grow our footprint of community-based participatory research – both in Los Angeles and abroad – via truly bidirectional interactions that actively involve members of society in planning research and uncovering solutions that prevent disease and advance overall well-being. The Department and the Institute on Inequalities in Global Health, which is directed by our faculty, hosted USC’s first ever global health symposium. The event brought together scholars from across USC and the world for an afternoon of sharing our work and developing new partnerships. And throughout everything mentioned, students are involved in hands-on capacities, as training the next generation of health leaders continues to be at the heart of our mission. There is so much more – including many stories you’ll find enriched with links to faculty videos and to podcasts, which are part our new series, “Preventive Pros.”

On the other hand, the world feels more unsettled than ever. It is impossible to ignore the wars raging in Ukraine, Gaza and elsewhere; the agony of the many, and many more who have been rendered homeless here in California and elsewhere in the United States; the plight of the estimated 110 million refugees world-wide who have been forcibly displaced as a result of persecution, conflict, violence, human rights violations or other catastrophic events; and the challenges posed to addressing these and other problems by stressed governments and the toxicity of today’s political and civil discourse. 

It may feel overwhelming. And yet, we are playing a critical role in providing the foundation for near-term as well as long-term solutions. Through our research, education and service, we are providing the evidence and the professionals who can render populations healthier and more resilient to the stresses of modern life and strife. Our work addressing deep-rooted disparities in health and healthcare access reduce some of the very inequalities that create social tensions and conflict. We have even begun initiatives to tackle the mitigation strategies that are needed to address climate change as a threat to health and well-being, and as one of the greatest public health threats of all time. 

In these pages, I hope you will find stories that can inspire you as we work together to advance discovery, innovation, collaboration and action in the name of population and public health. Thank you for visiting us and joining in this effort. 

Warmly and with gratitude,

Howard Hu, MD, MPH, ScD

Department launches continuous learning initiative for antiracist curriculum change

The Department of Population and Public Health Sciences at Keck School of Medicine of USC has launched the Fellowship in Continuous Learning for Antiracist Curricular Change (CLARCC), a cohort-based curriculum initiative focused on fostering a culture of self-reflection, learning and continuous improvement to advance racial equity. The initiative aims to strengthen the ability of participants to embed principles of antiracism into educational efforts.

Two cohorts comprised of six to twelve faculty and staff members from the Department meet over five months in either fall 2023 or spring 2024. Each group embarks on a guided journey of self-reflection and personal growth, followed by a structured commitment to embed antiracist principles in their educational work. It is through this that the Department hopes to provide a more inclusive educational experience to its students.

Hear more on creating sustainable antiracist curricular change

“There are specific indicators of cultural change that we are aiming for with this initiative,” says Jonathan Cohen, JD, MPhil, clinical professor of population and public health sciences, director of policy engagement at the USC Institute on Inequalities in Global Health, and CLARCC faculty coordinator. “One of them is that faculty who participate in this will feel more confident in applying antiracist principles to their courses and educational offerings.”

Fellows will receive continued group training, individual coaching, and peer-to-peer support toward success in implementing the new practices they will develop. “It’s very much designed in a spirit of adult learning, recognizing that different people learn in different ways,” says Cohen. “By offering people different modalities of support, we expect that everyone will respond in a way that makes sense to them.”

"These fellows are leading the way for all of us in the Department to make our learning environments as inclusive and effective as they can be."
– Jonathan Cohen, JD, MPhil

The fellowship is one of several efforts organized by the Department’s REDI Council – a dedicated team of faculty, staff, and students – and is part of the national Transforming Academia for Equity (TAE) Initiative supported by the Robert Wood Johnson Foundation. The initiative also complements a number of ongoing curricular reform efforts, echoing USC’s larger culture shift and diversity, equity and inclusion efforts in recent years. “Creating an inclusive educational and research environment requires all of us to learn new and better ways of interacting,” says Ricky Bluthenthal, PhD, associate dean for social justice at Keck School of Medicine and vice chair for diversity, equity and inclusion in the Department. “These fellows are leading the way for all of us in the Department to make our learning environments as inclusive and effective as they can be.”

The CLARCC initiative is an intentional response to requests from USC public health students; these include addressing the impact of racism and colonialism on health and public health in courses, increasing diversity in instructors and in curriculum, and embracing cultural sensitivity.

Through CLARCC and other efforts, the Department looks to ensure that those most impacted by curricular decisions have a voice and influence in shaping the learning experience. “Students feel their needs are seen and experiences acknowledged when faculty and staff support programs of antiracism and inclusivity,” says Roberta McKean-Cowdin, PhD, professor of clinical population and public health sciences and vice chair for education in the Department. “Many of our faculty are bringing their knowledge of health disparity and structural racism into classroom discussion, and initiatives like CLARCC help all of us learn to do this better and with greater understanding.”

Student Profile: Finding a love for public health work in Africa

Growing up, Abigail Kim moved around a lot—

And she hasn’t stopped since. During one summer in high school, she went on a trip to Nairobi, Kenya where she attended an international science camp. “I had a family friend who was a Professor in Public Health in nutrition, and she invited me to travel with her class. This was my first exposure to Public Health, and I just felt as though the work she was doing was impactful,” she reveals. “I really enjoyed that experience.”

After high school, she applied to USC—“This was one of the only programs I applied to that explicitly had a global health program at the undergraduate level.”

Her first internship would take her back to East Africa. In collaboration with Uganda Village Project, a nonprofit, she was assigned to a team of local and international students contributing to a 10-week rural assignment. Their mission was a health surveillance activity to learn about various health needs including malaria, HIV, family planning, obstetric fistula, and Water, Sanitation and Hygiene (WASH) programs. It was here that she started to build partnerships with village health teams and community members and decided to pursue a Master of Public Health at USC.

She returned to Uganda with the Global Research, Implementation, and Training (GRIT) Lab, under the mentorship of Heather Wipfli, PhD, Director of the Health Promotions Undergraduate program. Wipfli launched the youth ambassadors’ program in Northern Uganda, where Kim began to take on various leadership roles. During the pandemic, she hosted virtual workshops alongside University of Makerere students, to teach the ambassadors basic public health skills to conduct community health assessments.

“It’s been the most hands on you could ask for as an undergraduate or a master’s student,” she shares. The GRIT Lab provides students with an opportunity to conduct research from start to finish. Since her junior year, Kim has been involved in “protocol development, Institutional Review Board (IRB) approval, data collection, analysis and writing papers,” she explains. She was the lead author in her first paper ‘Community-Based Participatory Research: A Cross-Sectional Study Understanding Malaria in Rural Northern Uganda’, and is currently writing a second paper on ‘Assessing Community Perceptions on the State of Nutrition in Northern Uganda.’

Hear more about GRIT Lab's work in Uganda

“I decided a qualitative study would be interesting to understand the national nutrition strategy in relation to implementation at the local level, and also to understand the perspectives of residents” she divulges.  So, she conducted focus groups with various community members and famers and led key informant interviews which a variety of stakeholders. She will publish her findings later this year.

“Abigail is one of the most productive and professional students that I have worked with in my 20 years in faculty,” asserts Wipfli. “She has a very bright future ahead of her in global health research practice. Her skills and experiences in research and epidemiology, and her ability to connect and work with the community will get her far in the field.”

After graduation, Kim will be attending medical school at the University of California, San Francisco. “Health is so much more that treating. I want to help create structures or systems where people are more supported earlier on in their health journey,” she claims. 

Kim’s advice for students interested in traveling abroad is to “be flexible and hold things loosely—things are always changing on the go and may unexpectedly turn into something else—especially in public health,” she remarks. “That—and carry bug spray!”

USC geneticist Marlena Fejzo named one of Time magazine’s 2024 ‘Women of the Year’

The recognition follows the Keck School of Medicine professor’s recent study that showed that a hormone produced by the fetus triggers nausea and vomiting during pregnancy.

A new USC and University of Cambridge study finds that a hormone produced by the fetus – and a mother’s sensitivity to the hormone – are the cause behind nausea and vomiting of pregnancy, which, in its more extreme form can put the mother and fetus at risk.

The findings, which appear in Nature, suggest that pre-pregnancy exposure to the hormone might mitigate symptoms in some women.

Nausea and vomiting have long been a forgone conclusion for expectant mothers, affecting 80% of women at some point during pregnancy. An additional 2% experience an extreme form called hyperemesis gravidarum (HG) that can lead to weight loss, dehydration and hospitalization. But little has been known about the cause. Recently, a growing body of evidence has linked the symptoms to GDF15, a hormone produced in the placenta that increases substantially during pregnancy.

The new study supports the causal role of GDF15 in pregnancy sickness and reveals the role a woman’s sensitivity to the hormone has in determining the severity of her symptoms. Women exposed to lower levels of GDF15 before pregnancy experience more severe symptoms.

“We now know that women get sick during pregnancy when they are exposed to higher levels of the hormone GDF15 than they are used to,” said Marlena Fejzo, PhD, a clinical assistant professor of population and public health sciences in the Center for Genetic Epidemiology at the Keck School of Medicine and the paper’s first author.

Women who are more sensitive to the hormone get the sickest, said Professor Sir Stephen O’Rahilly, MD, co-director of the Wellcome-Medical Research Council Institute of Metabolic Science at the University of Cambridge, who led the collaboration. “Knowing this gives us a clue as to how we might prevent this from happening.”

Lowering GDF15 is one way to potentially address pregnancy sickness—and the present study provides the first human evidence that it is likely safe to do so. Another way to reduce symptoms involves exposing women to GDF15 prior to pregnancy, to “prime” or prepare them for elevated levels of the hormone once they become pregnant.

“This study provides strong evidence that one or both of those methods will be effective in preventing or treating HG,” Fejzo said.

$20 million grant from the National Cancer Institute enables research into youth e-cigarette and oral nicotine use at USC

USC faculty members Adam Leventhal, PhD and Caryn Lerman, PhD have received a $20 million grant for research to inform government regulations overseeing tobacco and its marketing, with a focus on protecting young people. The USC Tobacco Center of Regulatory Science (TCORS), an interdisciplinary initiative led by the USC Institute for Addiction Science (IAS), USC Norris Comprehensive Cancer Center and the Department of Population and Public Health Sciences at the Keck School of Medicine of USC, is one of seven programs nationwide to receive funding provided jointly by the Food and Drug Administration (FDA) and the National Cancer Institute, part of the National Institutes of Health (NIH). USC TCORS was launched in 2013 with FDA and NIH support and was renewed in 2018. This new grant continues the center through 2028.

With the new federal funding, USC TCORS expands its portfolio to focus on the ways a range of tobacco products other than conventional cigarettes are used by and marketed to young people. These products include e-cigarettes and commercially marketed flavored nicotine pouches, gums, lozenges and gummies. The center’s role is to provide rigorous evidence that guides FDA action in response to a fast-changing landscape of tobacco product offerings — and trends among adolescents and young adults.

"A center like TCORS is more than the sum of its parts. By connecting different types of research, we can uncover a body of evidence that fits together to surpass the high threshold that the FDA requires to change federal policy."
Adam Leventhal, PhD

“Multi-study center grants like this are critical to pushing the field forward,” said USC TCORS co-director Adam Leventhal, PhD, professor of population and public health sciences at the Keck School of Medicine and director of the USC IAS. “A center like TCORS is more than the sum of its parts. By connecting different types of research, we can uncover a body of evidence that fits together to surpass the high threshold that the FDA requires to change federal policy.”

Gathering the evidence to prevent harm to youth

Exposure to nicotine and other chemicals in e-cigarettes may interfere with the development of brain pathways that control attention, concentration and mood. Sound policy that minimizes use of e-cigarettes and other tobacco products among young people can have long-lasting health benefits on a large scale.

“Reducing exposure to novel nicotine products through evidence-based regulation is vital to improve health,” said USC TCORS co-director Caryn Lerman, director of USC Norris Comprehensive Cancer Center and associate dean for Cancer Programs. “USC TCORS researchers have a unique opportunity to influence policy that supports the well-being of generations yet to come.”

What community means to us

people outside dancing

Engaging in dedicated efforts to foster bidirectional relationships with the diverse communities that make up the tapestry of Los Angeles and beyond.

Our department’s mission of community engagement goes beyond mere dissemination of information and outreach through collaborations with over 150 culturally and ethnically diverse community partners. We recognize the strengths that diversity brings to our efforts and embrace the uniqueness of the various populations we work with. Each day, we honor our commitment to act upon socio-determinants of health - from addressing food insecurity, to developing a young adult workforce, to conducting community-based and participatory research, and more. Together, we are moving science to the forefront in advocacy and policy for informed decision making and developing outreach, engagement, and dissemination efforts locally, nationally, and globally. We strive to ensure our outreach efforts are inclusive and impactful to all members of society.

While located physically in the heart of Los Angeles, we are not limited by geographic boundaries. Modalities we have used to transcend geography and traditional boundaries of scientific communication include edutainment, digital media outreach, multimedia, multi-sectorial participation, and various culturally specific models of community engagement. We engage community health workers and promotores de salud, community leaders and champions, who – though sharing their wisdom and knowledge – allow us to participate in co-learning processes in our communities. In turn and in a timely fashion, we share the most recent scientific discoveries and community knowledge via dissemination of health and wellness information, trainings, civic engagement, and public action. We work earnestly to understand the unique needs, perspectives, and challenges faced by different communities, and value collaboration to achieve healthier, more resilient individuals; rich, diverse, and thriving communities; and solutions for public health threats and health equity challenges.

As we delve into community-focused initiatives and various efforts, we invite you to join us on this transformative path. We invite your engagement as we collaboratively create lasting impact that reverberates across our diverse neighborhoods. Together, let's continue to build and strengthen the future of community science actively shaping the health and well-being of a vibrant Los Angeles and beyond.

Zhongzheng Jason Niu selected as USC Sustainability Fellow to investigate the effects of air pollution exposure across life stages

Zhongzheng “Jason” Niu has been selected to USC’s first cohort of Presidential Sustainability Solutions Fellows. Niu, a post-doctoral fellow in the Department of Population and Public Health Sciences at the Keck School of USC, is an environmental epidemiologist studying extreme heat and air pollution exposure’s effect on health outcomes at the body and cellular level.

Engaging with our neighbors

Community partnerships ignite local impact

As a nexus for academic medicine, the Keck School of Medicine of USC fosters solutions for the biggest problems in human health through the traditional pillars of education, research and care. Its links to the communities living alongside USC’s campuses in Los Angeles — one of the most diverse cities anywhere — has led to local impact becoming its fourth pillar. “We’ve wanted to be the best neighbors possible,” said Lourdes Baezconde-Garbanati, PhD, MPH, a distinguished professor of population and public health sciences and the Keck School’s associate dean for community initiatives. “Part of that is the responsibility to elevate health and reduce the burden of disease in our surrounding communities.” Collaborating with the people they seek to serve is foundational to the efforts of faculty, trainees and staff. The Keck School maintains 32 active partnerships with organizations that promote health and wellness in the Los Angeles area.

Training-the-trainer to deploy community health educators

CoGENES Training Program is a community liaison participant engagement initiative

The CoGENES (Community Genetic Navigation Engagement Specialists) Training Program utilizes train-the-trainer model to train and deploy community health educators (CHE) and promotores de salud as a local workforce of community engagement specialists to improve communication on genetic research, clinical genetic testing and counseling to Hispanic populations. The goal of the program is to advance reductions in cancer disparities by promoting participation in genetic research at the community level and addressing knowledge, attitudes, beliefs, behaviors, and communication gaps related to donation of biospecimens, genome characterization, collection of family history, and clinical genetic testing with genetic counseling.

Influencing policy and practice in California

USC faculty member Max Aung, PhD, shares research expertise at California Attorney General’s press conference

Max Aung, PhD, assistant professor of population and public health sciences, was invited to speak at a press conference hosted by California Attorney General Rob Bonta. Bonta warned companies of their responsibility to disclose the presence of dangerous PFAS under Assembly Bill 1200 (AB 1200). “The role of an environmental health researcher in the policy space is to strengthen the evidence base with studies,” advises Aung who is an environmental epidemiologist.

Professor Jeffrey Klausner, MD, MPH, testifies at Cancer Prevention Act hearing

Jeffrey Klausner, MD, MPH, professor of clinical population and public health sciences, testified during a health assembly on The Cancer Prevention Act in Sacramento. The bill is part of an effort to increase uptake of the human papillomavirus (HPV) cancer vaccine in California. “Dr. Klausner has been a valued partner over the years in our learning about vaccinating Californians against the cancer-causing Human Papillomavirus, and most recently in crafting and refining AB 659, The Cancer Prevention Act.  His expert advice and testimony are essential to our success in the legislative process,” said California State Representative Cecilia Aguiar-Curry (D-Winters).

Claradina Soto, PhD, MPH, testifies on behalf of Native people

Claradina Soto, PhD, MPH, associate professor of clinical population and public health sciences, is Navajo and Jemez Pueblo, and recently testified in her capacity as a behavioral health scientist to the United States Senate Committee on Indian Affairs regarding the fentanyl crisis in Native communities.

Serving Global Communities

Youth Ambassador Program: community-led research in Uganda

Heather Wipfli, PhD and USC GRIT Lab organized weeklong interactive summer camps for children in Uganda, which they have done for eight years running. The program featured fun and energetic soccer training provided by Ugandan coaches, alongside public health workshops led by GRIT Lab and Makerere University students. “The camps were a really powerful tool which provided great role modelling by the college students for the younger kids,” says Wipfli.

Howard Hu, MD, MPH, ScD, lends expertise in lead to UNICEF's 'Healthy Tomorrows' series

Healthy Tomorrows is "a video series interviewing experts from around the world on children's environmental health issues," according to UNICEF's Children's Environmental Health Collaborative.

Durex and USC collaborate on a global initiative on sexual freedom promoting inclusivity

The Durex x USC Institute on Inequalities in Global Health Global Initiative on Sexual Freedom has emerged in response to the regression and denial of sexual health, rights, and freedoms occurring worldwide. With capacities in policy and advocacy, education, and research, the Initiative aims to address the structural and social barriers that impede understanding and expression of our whole sexual selves, to promote physical, mental, and social wellbeing for all, and to create a more just and inclusive society. The project includes three primary components – research, education and policy engagement – as well as an in-built evaluation. The primary countries are US, UK, Brazil, and Kenya, but it is also a global initiative.

Implementation studies on HIV prevention from Southern California to hard to reach populations in India

USC researchers are studying barriers to PrEP (pre-exposure prophylaxis for HIV prevention) at home and abroad. Proyecto FACIL and Heart PrEP aim to explore barriers and formulate strategies to implement and support gaps in PrEP uptake and adherence. In India, project goals are to model barriers and facilitators at the policy, structural, and organizational levels for implementing PrEP within targeted interventions for key populations in India; to assess patient and provider preferences for a novel PrEP care strategy; and to test the feasibility, acceptability, and sustainability of the novel PrEP care strategy.
