Kenneth Thummel received his Ph.D. in Pharmaceutical Science from the University of Washington in 1987 and completed a post-doctoral fellowship in Pharmacology at the University of Connecticut Health Science Center. In 1989, he was appointed to the University of Washington School of Pharmacy faculty, promoted to the rank of Professor in 2001 and was Chairman of the Department of Pharmaceutics between 2006 – 2019. He currently holds the title of Professor of Pharmaceutics and is an Adjunct Professor in the UW Department of Environmental and Occupational Health Sciences. Dr. Thummel’s research interests include the elucidation of genetic, hormonal and environmental factors that contribute to interindividual differences in xenobiotic biotransformation, in particular, intestinal cytochrome P450 3A-mediated first-pass drug metabolism, as well as gene x diet modifiers of drug response in Alaska Native and American Indian people. Dr. Thummel is a Fellow of the American Association for the Advancement of Science and the American Association of Pharmaceutical Scientists, and the recipient of the Rawls-Palmer Progress in Medicine Award from ASCPT. He is a Past-President of the American Society for Pharmacology and Experimental Therapeutics.
