Medical Outreach Lead, Bayer

Expert Bio

I am an emergency medicine physician and medical toxicologist with a long-standing interest in global health. After completing my Toxicology Fellowship at NYU in 2006, I returned to Washington University in St. Louis and started an ACGME accredited fellowship in Medical Toxicology. Over the following ten years, I became increasingly involved with global health and humanitarian relief projects. Some efforts include organizing a relief mission to Haiti after the 2010 earthquake, starting the scholar track in global health for the Washington University Division of Emergency Medicine, and becoming one of the Global Health Scholars for the Department of Internal Medicine. 


In July of 2016, I started working as the Medical Outreach Lead for Monsanto, now Bayer Crop Science, a global seed company with innovative technology that has great potential to remediate malnutrition. I remain on the faculty of Washington University and still an active member of the Toxicology team there. I lecture nationally and internationally on a diverse range of topics in medical toxicology and global health.
