Dr. Helke is currently a professor and Chair of the Department of Comparative Medicine at the Medical University of South Carolina. While there, she has completed several studies for biomedical companies in which she evaluated mice, rats, dogs and pigs for toxicologic changes to novel therapeutics and adverse reactions to both biomedical materials and devices. She also works closely with researchers to develop animal models and pathologic analysis of these models. Keith Nelson has over 15 years experience in toxicologic pathology, working for multiple contract research organizations. He completed his undergraduate and DVM degrees at Michigan State University before spending a year at Oregon State University studying fish immunology and a year in Kenya studying hyena behavior. He then completed his residency and PhD training at Colorado State University, after which he joined MPI Research, intending to "try out? toxicologic pathology. Almost two decades later, he remains excited about the field and has served as a pathologist, leader and mentor at large CROs, and adjunct assistant professor at Michigan State University. He is active within the field of anatomic and toxicologic pathology, holding multiple committee leadership positions in STP and ACVP, serving on the INHAND Minipig committee for harmonization of nomenclature, and publishing and presenting on a wide range of pathology topics. Aaron M. Sargeant is a Scientific Director, Pathology at Charles River Laboratories in Spencerville, OH, USA.
