Research Interests: 
My research focuses on the response of crustaceans to the neurotransmitters, neurohormones, hormones, and pheromones that regulate critical events in the life cycle of these organisms. These events include development, maturation and growth via molting, mating and the process of de- and re-calcification, reproduction, and the hormonal regulation of stress responses caused by internal and external changes in their environment. In particular, I study the mechanism of ecdysis (adult ecdysis, adult Carcinus molting video clip, hatching). This is a fascinating and critical step in life cycle since there is no somatic growth or, in some cases, mating without shedding the old shell. Using the tools of biochemistry, physiology and molecular biology, my aim is to isolate and identify/characterize the structures and functions of these chemical mediators. Moreover, I attempt to understand how these events occur at the cellular, tissue, and organism level in order to enhance the stock of the blue crab (Callinectes sapidus) and also regulate the growing number of foreign species such as the Atlantic green shore crab (Carcinus maenas).
