Education

2000  M. Chem. Master of Chemistry, Minor in American Studies - University of Sussex (U.K.)

2006  Ph.D. Chemical Oceanography - Massachusetts Institute of Technology (MIT) and Woods Hole Oceanographic Institution (WHOI)

2007-2009  Postdoctoral Fellow, Microbial Science Initiative - Harvard University

Research

My research explores the persistence of human‐derived compounds in the marine environment, specifically those from oil and plastic waste. I am interested in understanding how the chemical structure, physical associations and the bioavailability of chemical compounds determines their cycling and eventual fate. I enjoy collaborating with students who have wide ranging interests related to the ocean and the environment.

Funding

Our research group at Haverford has been supported by funding from the National Science Foundation (NSF), the American Chemical Society Petroleum Research Foundation (ACS-PRF), the Gulf of Mexico Research Initiative (GoMRI), the National Academies of Sciences, Engineering and Medicine Gulf Research Program (GRP), and the Camille and Henry Dreyfus Foundation.
