My research has focused on the biology of marine larvae and early juveniles. I am particularly interested in the physical and biological factors that drive year-to-year variation in populations of ecologically and commercially important fish and crustaceans. My work has involved a combination of field observation, laboratory experimentation, and mathematical modeling. I am planning to retire in 2015 and will not be accepting new students for the fall term of 2014. However, I will be available to serve on graduate-student advisory committees for the foreseeable future.
Ecology of non-indigenous crab species in the Middle Atlantic Bight.
My present work investigates processes that control the establishment and spread of invasive crab species in coastal and estuarine habitats. Present studies focus on the Asian shore crab (Hemigrapsus sanguineus. One area of particular interest concerns the resurgence of native crab species in areas that had previously been colonized by invasive populations of Asian shore crabs. These studies incorporate high-frequency measurements of larval settlement in habitats where invasive and native species co-occur, as well as intensive surveys of changes in the relative abundance of these species over time.
