Education and Employment: B.S. City College of the City of New York, 1952;  M.S. Brooklyn College, NY, 1954; Ph.D. Cornell University, 1957; Postdoctoral study: National Research Council Fellow, Carnegie Institution of Washington, Dept. of Embryology, 1957-1959. Assistant Professor, Biology Dept. Johns Hopkins University, Baltimore, 1959-1965. Associate Professor, University of Connecticut 1965-1972.  Professor, Molecular and Cell Biology, 1972-1998.  Research Professor, 1998-.

Research Interests: Gene regulation during development and reproduction; hormonal and molecular interactions; comparative endocrinology of invertebrates.
(1) studying hormones affecting reproduction, morphogenesis and metamorphosis of invertebrates and
(2) developing crustacean aquaculture techniques.
We are particularly interested in elucidating the signal transduction pathways involved in the regulation of reproductive development in invertebrates, especially Crustacea and Annelids.
