Research:
My field of interest is animal physiology, particularly in the
areas of biomineralization, osmoregulation and
membrane transport. The major emphasis of my research involves the control of
calcification in the Crustacea and the mechanisms of
ion translocation to and from skeletons.
Graduate students in my lab have worked on problems involving crustacean
mineralization, crustacean gill structure and ion transport, crustacean
salinity and temperature preference, hormonal control of molting in isopods,
and bone physiology.
