Health Equity and Translational Social Science (HETSS)
DGSOM’s newest research theme aims to create equity-centered patient care models. Under the leadership of co-chairs Rochelle Dicker, MD and Helena Hansen, MD, PhD, the theme, established in 2020, continued inspirational work to transform healthcare knowledge and practice and shift to a sociomedical paradigm.
- The HETSS Seminar Series. Co-sponsored by the Rangell Social Medicine Grand Rounds, the seminar series featured more than 20 presentations on topics ranging from “Structural Racism in Biomedical Research” to “Addressing Historical Trauma in Marginalized Communities.” View the recording on our Youtube Playlist.
- In June 2022, HETSS collaborated with the Lancet Commission on U.S. Public Policy and Health to launch the Health Justice Seminar Series. Recordings of this series can be found here.
- Social Medicine Collab. In partnership with Charles R. Drew University of Medicine and Science, the Collab uses human-centered design to engage low-income transitional-age youth (18-25 years old) in South L.A. in redesigning health services to be delivered in communities where they congregate. The design process has yielded plans for services at youth-serving organizations in South L.A. via a Charles R. Drew University mobile health clinic van. The clinic service sites will host peer health workers and wellness workshops embedded in art and athletic events, as well as musical and dance performances that are focused on mental health, sexual health, and addictions.
- HETSS Newsletter. The newsletter disseminates information regarding health equity resources, funding opportunities, event announcements and features a community spotlight.
- Health Justice Internship. HETSS worked with UCLA medical students to help launch this compensated opportunity for underrepresented minority high school students in California interested in healthcare careers.

- Pinpointing gender-specific differences that may contribute to heart disease and the cardiac response to COVID-19.
Immunology, Inflammation, Infection and Transplantation (I3T) theme members collaborated across disciplines to advance COVID-19 research.
Members of the I3T theme collaborated with other themes and disciplines to make critical contributions to understanding the fundamental virology and immunology of SARS-CoV-2 and to uncovering translational insights and potential therapies.
- The outcomes of 50 children treated with gene therapy for a lethal form of inherited immune deficiency were published in the New England Journal of Medicine (NEJM); this clinical trial reports greater than 95% event-free survival and 100% overall survival.
- A DGSOM Seed grant was awarded to I3T faculty to support novel PET imaging approaches to measure responses to viral gene therapies.
- A team of UCLA immunologists and transplantation surgeons reported how T cells respond in patients who have received a hand transplant.
The Metabolism Theme established new core facilities to promote research and discovery. The new cores support Mitochondrial Imaging and Mitochondrial Biochemistry and are joining the already established cores of Bioenergetics and Metabolism, Metabolomics, Lipidomics, and Physiology. The cores are providing expertise, training, technical experimental consultation, and leading-edge equipment.
The theme continues to run its interactive activities which include the Know-Your-Colleague series, the Metabolism Interest Group, Super-Mito events, and the UCLA Mitochondria Symposium.
