Research Interests

My research program addresses societally relevant and globally significant issues concerning the assessment of diverse anthropogenic activities including land-use and watershed development impacts on aquatic environments, the consequences of marine mineral and energy extraction, and the benthic distribution and impacts of marine debris (microplastics). I utilize sedimentological, radiochemical, micropaleontological, and biogeochemical tools to assess high-resolution sedimentary sequences that document the changing structure and function of benthic and planktic ecosystems.
