Paul Tsang

Professor of Molecular, Cellular and Biomedical Sciences

Ph.D. Boston University, 1986

Research Areas

Reproductive physiology of elasmobranchs (sharks and skates); steroid hormone function

Research Emphasis

My primary area of research is the reproductive biology of elasmobranch fishes, sharks and skates. My focus is to use multiple biochemical/molecular/morphometric endpoints, e.g. blood and tissue steroid hormone concentrations, gonadal dynamics and reproductive tract dynamics, to study the biology of reproduction. In addition, our work also includes other assessments of elasmobranch life history parameters, such as age and growth, movement patterns (using pop-up satellite technology) and population structure (using microsatellite and mitochondrial DNA). Our group includes undergraduate and graduate students, and research collaborators from the Marine Science Center at the University of New England.
