Leeka I. Kheifets

Dr. Leeka Kheifets is a Professor of Epidemiology at the UCLA School of Public Health. She is widely known for her work in environmental and occupational epidemiology, and currently serves on several international and national committees that advise governments on environmental policy, including the Scientific Expert Group of the International Commission on Non-Ionizing Radiation Protection (ICNIRP). She has also served on committees of the Swedish Radiation Protection Authority (SSI), the National Academy of Sciences, Institute of Electrical and Electronics Engineers, National Council on Radiation Protection and Measurements, National Institute of Environmental Health Sciences, International Agency for Research on Cancer, and World Health Organization Working Groups. Prior to her professorship at UCLA, she was Head of the Radiation Studies Program at the World Health Organization and was a Technical Executive at the Electric Power Research Institute, where she directed a multi-disciplinary electric and magnetic fields (EMF) research program. She has taught at the Stanford University School of Medicine in the Department of Health Research and Policy, and has over 100 publications. Her current interests include innovative epidemiologic methods for studying risk factors for childhood leukemia, occupational exposures and ALS, development of policy in the face of uncertainty, and potential health effects of cell phone use and other non-ionizing radiation exposures.
