I grew up in Wales and received my PhD in Marine Biogeochemistry from Newcastle University (Newcastle, England). After that I did a postdoc at Old Dominion University (Norfolk, VA) before becoming a professor at Skidaway Institute of Oceanography (UGA, Savannah, GA). Finally I moved to Northeastern in 2018. I study the natural carbon cycle, how humans are altering it, and plastics in the environment. I see plastics as a novel component of the carbon cycle as well as potential pollutants.
