Heidi Pickard is a PhD student in the Sunderland lab at Harvard's John A. Paulson School of Engineering and Applied Sciences. She holds a Master's degree in Chemistry from Memorial University in Newfoundland, Canada, where her research focused on the long-range transport mechanisms of perfluoroalkyl substances. She also holds a Bachelor's degree with Honour's in Analytical Chemistry from Mount Allison University in New Brunswick, Canada. Her current research focuses on developing tools to better assess human exposure risks to per- and polyfluoroalkyl substances (PFAS). This includes further investigating the fate and transport of PFAS in the aquatic environment, as well as trying to better understand factors that affect bioavailability of different PFAS and their bioaccumulation and trophic transfer in aquatic organisms consumed by humans.
