My research focuses on reproductive endocrinology, behavior and development of aquatic animals, with a current emphasis on manatees. I have experience in developing and validating steroid hormone assays for various species, including mammals and birds. I have on-going studies measuring reproductive and stress related hormones, correlating hormone concentrations and behavior in manatees, and histological analysis of manatee embryology.
