Dr. Li has extensive experience addressing toxicology, human health risk assessment, and other regulatory science issues for pesticides, industrial chemicals, medical devices, and pharmaceuticals. Her particular strengths include identifying and understanding key scientific issues that affect regulatory risk assessment decisions (i.e., application of uncertainty and FQPA/PCPA factors, benchmark dose, CxT analyses, and cumulative risk assessment). 

Dr. Li has considerable experience in design, project management, and analysis of toxicology studies. She has expertise in the toxicity and risk assessment of neonicotinoids, organophosphates, ethylene oxide and bisphenol A.

Prior to joining Exponent Inc., Dr. Li was Senior Science Fellow at Monsanto, providing expertise in toxicology/risk assessment. She led the neurotoxicology group at Monsanto's Environmental Health Laboratory where she conducted pharmacokinetic, toxicology, and neurotoxicology studies for industrial chemicals, agricultural products, and pharmaceuticals. These studies included guideline and specialized mechanistic studies, as well as human and in vitro studies.

Dr. Li's current research interests include evaluating the neurotoxic potential of industrial and agricultural chemicals and application of quantitative risk assessment approaches and statistical methods to toxicity endpoints. Dr. Li served on the National Academy of Science's National Research Council Committee on Toxicity Testing and Assessment of Environmental Agents in the 21st century, and multiple EPA Science Advisory Boards (SAB), including recent appointments to evaluate research on hydraulic fracturing and the toxicology and risk assessment for chemicals. She has served on international and national panels on the integration of in vivo and in vitro screening methods and development of databases for prioritizing chemicals for further testing and regulatory decision-making. She has been a member of several International Life Science Institute Committees on adult and developmental neurotoxicity testing (DNT), and toxicity testing strategies for pesticides. Dr. Li served on the U.S. expert teams to the Organization for Economic Cooperation and Development (OECD) for the development of international test guidelines for adult and developmental neurotoxicity testing. She received her Ph.D. in pharmacology and physiology from the University of Chicago. 

Dr. Li was President of the Neurotoxicology Specialty Section and Chair of the Specialty Section Collaboration and Communication Group of the Society of Toxicology.
