Bridger is a 5th-year PhD candidate in Environmental Science and Engineering where he is researching the chemistry of toxic chemicals and their environmental behavior. He is also pursuing a master’s degree in Applied Math.

Bridger’s research focuses on understanding the biogeochemistry of per- and polyfluoroalkyl substances (PFAS), a class of compounds referred to as "forever chemicals", in aquatic environments. He develops analytical frameworks and statistical models to infer PFAS chemistry and sources in a model watershed on Cape Cod, Massachusetts.

Originally from Denver, Colorado, Bridger completed his BS in Environmental Engineering with an energy conversions focus before joining the Linden Research Group. He worked on several projects, including the physical characterization and biological treatment of hydraulic fracturing wastewater.
