Brief synopsis of current research:
My general area of research interest is the reproductive physiology of teleost fish, with emphasis on related lipid metabolism. Specific interests include the physiology of gonad development, the composition of egg yolk lipids and the utilization of yolk by developing embryos and larvae. I am also interested in the lipid nutrition of larval fish. The work is relevant to both the basic science of reproductive biology and to aquaculture.
