Welcome to the homepage for the laboratory of Professor Peter M. Collins at the University of California at Santa Barbara in the department of Ecology, Evolution and Marine Biology. The research projects of this lab focus on the mechanisms regulating reproduction and development in vertebrate animal models, comparative reproductive endocrinology and fertility, reproductive physiology in teleosts, endocrine regulation of viviparity, evaluation of candidate species for mariculture, marine teleost larval rearing technology and the development of novel microparticulate diets for marine larvae.
