Research Interests
The work is centered on gene-environment-nutrition interactions in carcinogenesis. Why certain people are predisposed to environmentally caused cancer and how nutrition can counteract such elevated cancer risk. As research organisms we use yeast, mammalian cells and mice. Endpoints are mostly genetic instability, mutations, DNA single and double strand breaks, DNA repair efficiency and oxidative DNA damage.
Biography

Dr. Schiestl received his Ph.D. in Biology and Genetics from the University of Vienna, Austria, in 1983. He is currently a Professor of Pathology, Environmental Health and Radiation Oncology. Previously, he served as Assistant and Associate Professor in the Department of Cancer Cell Biology at the Harvard School of Public Health. He is Director of the UCLA Center for Environmental Genomics and a current member of the UCLA Cancer Center, UCLA Center of Occupational and Environmental Health, UCLA Interdepartmental Program in Molecular Toxicology (Faculty Advisory Committee), and UCLA ACCESS Graduate Program steering committee. He is also a member of the Planning Committee for the Environmental Mutagen Society meeting as well as Chair and Speak at the Symposium on "Genetic Instability" which will be held on March 11-15, 2003 at Miami Beach, Florida.
