Justin Teeguarden


Justin Teeguarden has been engaged in the field of toxicology since the late 80's. Since that time he has worked in a variety of capacities most of which involved some aspect of risk assessment and computational modeling. He received his Ph.D. in 1999 from the University of Wisconsin, Madison in Toxicology and went on to private industry to develop physiologically based pharmacokinetic (PBPK) models for a variety of compounds. Most of these models were used to evaluate the relationship between external exposure, target tissue dose and response. The motivation has been that quantitative models of dose-response that characterize the underlying physiological and biochemical processes are more sound, more flexible platforms for conducting interspecies, dose and dose-route extrapolations. He has received a number of awards, including two for publications advancing the science of risk assessment. Justin now works at Pacific Northwest National Laboratory in Richland, WA. where he came to continue following interest in the fundamental biology underlying dose-response relationships by developing models of signaling networks involved in important human environmental diseases. He previously served as a vice president for the DRSG.
