Biography

I received an M. Chem degree in Chemistry from the University of Sussex, U.K. in 2000 and a Ph.D. in Chemical Oceanography from the Massachusetts Institute of Technology and Woods Hole Oceanographic Institution (WHOI) Joint program in 2006. After teaching Oceanography at Boston University for a year, I was awarded a Microbial Science Initiative postdoctoral fellowship in 2007 from Harvard University. I joined the faculty of the Chemistry department at Haverford College in July, 2009 and am also a member of the Bryn Mawr and Haverford Bi-College Environmental Studies department. I enjoy working with students in the sciences, social sciences and humanities to consider the environment from a wide range of perspectives. I am particularly interested in using chemical and molecular biological approaches to examine the impact of human-derived chemicals on the oceans.

Research

My research interests are centered in the field of biogeochemistry, a multidisciplinary approach focused on understanding the chemical composition of the Earth’s biosphere. Within this broad area, my research examines the sources, sinks and cycling of organic matter. More specifically, I am interested in the persistence of human‐derived compounds in the marine environment (e.g. petrochemicals from oil and plastics). My work seeks to examine how the chemical structure, physical associations and bioavailability of specific organic compounds determines their cycling and eventual fate.

At Haverford, our group utilizes geochemical and microbiological approaches to examine the cycling of natural and anthropogenic carbon compounds in the environment. We have focused much of our research efforts on investigating the fate of petroleum in the Gulf of Mexico following the Deepwater Horizon oil spill. We have also expanded our examination of lingering oil in the marine environment to Prince William Sound, Alaska, where we are studying oil residues from the 1989 Exxon Valdez oil spill and the 1964 Alaska earthquake.
