Early life and education

Hernandez was born in Los Angeles and raised in neighborhoods shaped by migration and urban development, an upbringing linking her to figures and institutions such as Dolores Huerta, Cesar Chavez, East Los Angeles community organizations, University of Southern California, and California State University, Los Angeles. She completed a Bachelor of Arts at the University of California, Los Angeles where mentors connected her to programs affiliated with the Ford Foundation, National Institutes of Health, Centers for Disease Control and Prevention, and local public health departments. Hernandez pursued graduate training at the University of California, Berkeley where her advisors included faculty with ties to the Robert Wood Johnson Foundation, the Kaiser Family Foundation, and the American Public Health Association. Her doctoral work integrated methods from scholars associated with the Harvard T.H. Chan School of Public Health, the Yale School of Public Health, and the Johns Hopkins Bloomberg School of Public Health.

Research and career

Hernandez’s early career included appointments at municipal health departments and collaborations with organizations like the Los Angeles County Department of Public Health, the Environmental Protection Agency, and the National Oceanic and Atmospheric Administration on urban heat, air quality, and social determinants of health. She later held faculty positions that linked academic centers such as the University of California, Berkeley School of Public Health, the Columbia University Mailman School of Public Health, and the University of California, Los Angeles Fielding School of Public Health with community partners including Coalition for Clean Air, Asian Americans Advancing Justice, and Black Lives Matter chapters. Her interdisciplinary teams often included investigators from the Massachusetts Institute of Technology, the Stanford School of Medicine, the Princeton School of Public and International Affairs, and the London School of Hygiene & Tropical Medicine.

Hernandez developed community-based participatory research models drawing on methods from scholars linked to the MacArthur Foundation, the Wellcome Trust, the Gates Foundation, and the Rockefeller Foundation. Projects under her leadership used geospatial analysis tools developed with partners at the National Aeronautics and Space Administration, climate models from the Intergovernmental Panel on Climate Change, and urban policy frameworks influenced by the United Nations Human Settlements Programme and the World Health Organization. She has advised mayors, city councils, and task forces, including collaborations with the offices of the Mayor of Los Angeles, the New York City Council, and the City of Chicago Department of Public Health.

Notable publications and contributions

Hernandez has authored and co-authored studies published in venues comparable to journals edited by institutions such as the Lancet, the New England Journal of Medicine, and the American Journal of Public Health. Her work on heat vulnerability mapping and neighborhood-level exposures has been cited alongside reports from the Intergovernmental Panel on Climate Change, policy briefs from the Urban Institute, and white papers from the Brookings Institution. Collaborative reports she contributed to have informed initiatives at the World Bank, the Inter-American Development Bank, and the United Nations Development Programme.

Key contributions include methodological advances in participatory mapping co-developed with researchers affiliated with the Esri geospatial community, analytical frameworks building on the work of scholars at the National Bureau of Economic Research, and translational toolkits adopted by local health departments modeled on guidance from the Centers for Disease Control and Prevention. Hernandez has contributed chapters in edited volumes alongside authors connected to the American Sociological Association and the Association of Schools and Programs of Public Health.
