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.
