Guillaume Lhermie is a graduate veterinarian holding a MSc in Economics and a PhD in pharmacology and innovation. He moved to the U.S. for a two-year post-doctoral training in public health and epidemiology, where he was hosted in Yrjo Grohn’s lab. He was afterwards hired as Research Associate in the Department of Population Medicine and Diagnostics Science at Cornell University.
Before working in academia, Dr. Lhermie worked in private veterinary practice, as well as in the pharmaceutical industry, as R&D project manager and medical director. He is currently Assistant Professor in Animal Health and Veterinary Public Health Economics at University of Toulouse.

Research interests

​Guillaume Lhermie’s research focuses on One Health and Infectious Diseases issues at the interface of animal agriculture and human health. He is studying the economics of antimicrobial resistance at microeconomics (farm) and macroeconomic (national and global) levels. At the farm level, he conducts cost-benefit analyses of several curative or preventive strategies implemented by farmers, such as alternatives to antimicrobials, veterinary precision medicine, or insurance. At a macroeconomic level, he develops simulation models  to evaluate the impact of public policies targeting the reduction of drug inputs in animal agriculture, using dynamic modeling approaches of production systems. His most recent research emphasis has been studying antimicrobial use and resistance as a sustainability challenge, in which he developed qualitative and quantitative models aiming at analyzing the impact of antimicrobial use on social-ecological systems, and communicating to policymakers.  His research interests also focus on the strategic interactions of stakeholders at the frontiers of the agricultural system and human community. Overall,  Dr Lhermie is interested in assessing the efficiency of public policies, under a One Health umbrella.


Guillaume Lhermie’s teaching activities consist of a regular course in Animal Health Economics for undergraduate veterinarians and Master students; a regular course in Agricultural Economics for undergraduate veterinarians; and Systems Thinking in Veterinary Public Health Economics for Executives. He is in charge of coordinating the educational module data analysis and cattle production to be distributed to undergraduate veterinarians.
