Faculty: Jon Arnot, PhD

Adjunct Professor, Department of Pharmacology & Toxicology
President, ARC Arnot Research and Consulting

Jon Arnot is the President of ARC Arnot Research & Consulting and an adjunct professor in the Department of Physical and Environmental Science and in the Department of Pharmacology and Toxicology at the University of Toronto. He has 17 years of research experience in the development, application, and evaluation of databases, methods and models to assess the exposure, hazard, and risk of organic chemicals to humans and the environment. His research has focused on the application of high-throughput screening methods for prioritizing chemicals for risk assessment. He is the principal investigator or co-investigator of various international projects including collaborations in the United States, Europe, and Canada. Dr. Arnot served on the National Academies of Sciences, Engineering, and Medicine Committee on Incorporating 21st Century Science into Risk-Based Evaluations. He was the recipient of the James M. McKim III Innovative Student Research Award (2008) from the International QSAR Foundation to Reduce Animal Testing and the Society of Environmental Toxicology and Chemistry (SETAC) Best Student Paper Award (2009).  Dr. Arnot earned his PhD in environmental and life sciences from Trent University.
