I am interested in applied research, data synthesis and environmental policy. My current research seeks to inform marine policy and resource management through projects related to ecosystem services provided by shellfish. Shellfish can remove nutrients, improve water clarity, and provide habitat for a variety of fish and crustaceans. I work collaboratively with benthic ecologists, modelers, economists, members of the aquaculture industry, and environmental managers to quantify ecosystem services provided by a variety of species of cultivated shellfish:

  1. Shellfish and eutrophication reduction:  In eutrophic coastal areas that have an excess of nutrients and overabundance of phytoplankton, shellfish filter feeding can improve water quality. A recent paper that I co-authored quantified the environmental benefits provided by ribbed mussels grown on a commercial mussel raft in the South Bronx, NY, and a second paper modeled nitrogen removal provided by Connecticut’s oyster industry and calculated the dollar value to replace this service with traditional nutrient reduction approaches.  My colleagues and I have several ongoing projects that seek to document the nutrient removal services provided by shellfish.
  2. Finfish interactions with oyster aquaculture gear: Shellfish growers routinely observe fish at a variety of life stages interacting with aquaculture gear.  My colleagues and I have been exploring the use of underwater video technology to document fish interactions with oyster aquaculture cages in Long Island Sound. Data demonstrating habitat services provided to fish are valuable to regulators and fishery managers who make decisions about siting shellfish farms and protecting habitat for recreationally and commercially important fish species.  Videos of fish using oyster cages can also serve as compelling outreach tools to demonstrate environmental benefits provided by the shellfish aquaculture industry to the public.
  3. Shellfish aquaculture and water quality management:  The use of shellfish and/or seaweed cultivation and harvest to aid in the removal of nitrogen and other nutrients from the coastal environment has been termed “nutrient bioextraction”.  In addition to documenting water quality improvements provided by shellfish aquaculture, I am interested in contributing to the development of policies that give shellfish growers “credit” for the nutrient removal services they can provide to the coastal environment.  Since 2015, I have been a member of the Chesapeake Bay Oyster Best Management Practice Expert Panel, which is making a series of recommendations on the inclusion of oysters in Chesapeake Bay’s water quality regulatory process.  The panel’s first set of recommendations was approved by EPA in December 2016, and the panel plans to release multiple additional recommendations for public comment and programmatic review in 2018.  See panel recommendations and more information »
  4. Scientific guidance to environmental management: I have continued work from my previous position with the Long Island Sound Study as part of the Science and Technical Advisory Committee.  I also serve on the Connecticut Shellfish Initiative research work group.
