Research Interests

Behavioral Ecology, Animal Behavior, Marine Biology
I am interested in the influence of sexual competition on courtship and mating behavior, particularly in the blue crab, Callinectes sapidus. I am also interested in the potential impacts of fishing on blue crab reproduction. Currently, I am assessing the population structure (e.g., abundance, size distribution, sex ratio) and various measures of reproductive potential (e.g., sperm stores of both sexes, brood production and fecundity of females) of adult blue crabs in Barnegat Bay.
