Michael A. Kelsh, Ph.D., M.P.H.

Dr. Kelsh specializes in the application of epidemiology and biostatistics to occupational, environmental health, and pharmaceutical issues. Dr. Kelsh has extensive experience in the design, implementation, analysis, and interpretation of epidemiologic studies. Dr. Kelsh has conducted epidemiologic studies of occupational injuries, musculoskeletal diseases, cardiovascular disease, respiratory and neurological diseases, and cancer incidence and mortality. His research has also focused on exposure assessment issues, and as part of epidemiologic investigations, has evaluated the potential health effects of air pollution, arsenic, asbestos, beryllium, hexavalent chromium, electric and magnetic fields, ergonomic factors, mercury, perchlorate, radiofrequency energy, and trichloroethylene. Dr. Kelsh has conducted occupational health studies among a variety of worker groups including: Aerospace, electric utility, electronics, mining, and petroleum research workers. He has also worked on meta-analyses of trichloroethylene and cancer, arsenic and bladder cancer; auto mechanic work and mesothelioma; and magnetic fields and childhood leukemia.

Dr. Kelsh is an adjunct professor at the University of California, Los Angeles (UCLA) School of Public Health and teaches seminars in occupational/environmental epidemiology and exposure assessment. Dr. Kelsh has served on Scientific Advisory Panels covering a variety of environmental health issues for the California Department of Health Services, the New York Department of Environmental Health, and the Oregon Department of Human Services. Dr. Kelsh is fluent in Spanish and has international public health experience through consulting, research, and volunteer projects in Latin America.
