She is a graduate of Harvard University and holds a Ph.D. in isotope geochemistry from the University of Waterloo. Sherwood-Lollar's specialization is the application of stable isotope geochemistry to gaseous and aqueous systems. Current work focuses on investigation of the origin, transport, and transformation of carbon-bearing compounds and contaminants (including light hydrocarbons and organic solvents) in groundwater and soils.
