UCLA Fielding consists of five academic departments.

The UCLA Fielding School of Public Health consists of five academic departments and one interdepartmental degree program, each of which offers degree programs and features nationally and internationally renowned faculty who teach and train the next generation of public health leaders; conduct research at home and abroad that advances knowledge on public health issues; and partner with communities, policymakers, and experts across disciplines to implement evidence-based solutions that advance population health.

The school’s five academic departments reflect the major public health disciplines:

Biostatistics Masthead Visual


Biostatistics helps researchers in public health, medicine, and biology with: study conception and design, data collection and analysis, drawing conclusions, and dissemination of results. Biostatisticians develop statistical models and methods to collect and analyze data to help improve the health of people everywhere.

Environmental Health Sciences

Environmental Health Sciences explores the health risks associated with exposures to stressors in the ambient, built, and occupational environments, and the development, implementation and evaluation of science-based policies to address environmental and occupational health challenges and inequities. The department is also home to the Molecular Toxicology interdisciplinary graduate program, which explores the mechanisms of actions of toxicological agents and their impacts on health and the environment.

Health Policy and Management

Health Policy and Management seeks to enhance healthcare quality, access, cost and financing through research-driven policies and practices that improve the performance of health institutions in the U.S. and beyond. Molecular Toxicology seeks to characterize and elucidate the problems related to exposure to chemical agents, including the mechanisms by which exogenous chemicals and physical agents cause disease.
