Erin L Pulster, PhD

Dr. Erin Pulster is a Research Biologist at the Columbia Environmental Research Center.

Dr. Pulster studies acute and chronic anthropogenic contamination in aquatic ecosystems. Prior to joining USGS, she was leading the Marine Toxicology Lab at the University of South Florida’s College of Marine Science. Dr. Pulster studied the impacts of the Deepwater Horizon Oil Spill and the subsequent sublethal impacts on marine teleost. More recently her research focuses on levels of per- and polyfluoroalkyl substances (PFAS) in seafood and the potential associated human health risks from the consumption of contaminated foods. Dr. Pulster has worked on various projects investigating the extent of environmental contamination (e.g., polychlorinated biphenyls, pesticides, toxaphene, polycyclic aromatic hydrocarbons) in various matrices (air, water, sediment, passive samplers, biota) to evaluate sublethal impacts and estimate potential environmental and human health risks.

Current Projects:

  • LC/MS/MS analytical method development for PFAS.
  • PFAS extraction methodology for a variety of matrices (e.g., water, sediment, insects, passive samplers).
  • Measuring PFAS levels in recreationally important fish and assessing the need for consumption advisories.
  • Chronological temporal assessment of the distribution of PFAS in Gulf of Mexico sediment cores.
