Experts Interviewed

She is considered a pioneer in the area of PFAS occurrence and behavior and has focused on groundwater contaminated by fire-fighting foams and PFAS in municipal wastewater treatment systems and in municipal landfill. Current work focuses on the development of PFAS fingerprinting sources, characterizing PFAS in landfill gas, and PFAS on specialized textiles and other materials. She serves as an Executive Editor for Environmental Science and Technology.

His work has been funded by NSF, US DoD, US DOE, USBR, New York State, and several industry and foundations, and has been featured in media, including National Geographic, PBS programming and the National Institutes of Health, among others.

Her other research focuses on how information collected on an individual translates across higher levels of biological organization. Using fish as a model organism, she explores how changes in gene expression and the physiological processes occurring within an individual translate to behavioral changes and ecologically relevant endpoints such as reproduction and growth, how short term phenotypic changes in expressed traits alter long term genetic change and affect life history traits, and how anthropogenic influences such as contaminants and other stressors impact such relationships and affect populations or communities of fish.
