My research is focused on the interface between invertebrate aquaculture and the environment. I have a strong interest in the application of molecular tools to avoid adverse effects of aquaculture on ecosystems, and in applying knowledge gained from research to resource management problems. I am also interested in diagnosing and understanding the effects of large-scale natural and human-caused environmental changes on sentinel organisms in the marine environment.

My current research projects include:

  1. investigating local adaptation in the native Olympia oyster, Ostrea lurida, and the purple hinged rock scallop, Crassadoma gigantea
  2. assessing potential genetic impacts of farmed geoduck, Panopea generosa, on their wild counterparts
  3. developing sterilization techniques for cultured native shellfish
  4. creating breeding and broodstock rotation protocols for reintroductions

My research generally involves interdisciplinary approaches and I collaborate with diverse scientific specialists in academia, resource management agencies, and the shellfish industry.
