Donald Tillitt, PhD

Don has been at the Columbia Environmental Research Center (CERC) since 1989, then part of the U.S. Fish and Wildlife Service. He leads research on the effects of chemicals on fish and wildlife, with an emphasis on reproduction and development in fish. His research interests focus on developmental effects of persistent chemicals in fish. Multiple levels of biological organization are generally evaluated in his research efforts, with endpoints consisting of molecular, biochemical, histology, and behavioral-level effects. Recent research projects in his laboratory include: 1) effects of PCBs and dioxins on development in sturgeon species; 2) causes and effects of thiamine (vitamin B1) deficiencies on Great Lakes salmonines; 3) effects of endocrine disrupting chemicals on sexual differentiation and gonad development in fish; and 4) transgenerational epigenetic effects on endocrine disrupting chemicals across vertebrate taxa. Don has served in a variety of capacities for the Society of Environmental Toxicology and Chemistry, currently serves as an Editor for Environmental Toxicology and Chemistry. Don has adjunct professor appointments in the Biological Sciences and the School of Natural Resources at the University of Missouri. He serves on graduate student advisory committees, offers guest lectures, and has taught Environmental Toxicology since 1992.
