Current Research Interests 

Comparative molecular endocrinology, with emphasis on post-receptor signal transaction pathways mediating the actions of peptide hormones and neurotransmitters in fishes. Current focus is on the second messenger systems involved in gonadotropin-releasing hormone stimulation of gonadotropin and growth hormone release from cultured dispersed pituitary cells of the goldfish, as well as the receptor subtypes and mechanisms mediating biogenic amine actions on the release of these two pituitary hormones.
