My research areas are interdisciplinary, and include fish physiology, endocrinology and nutrition as they relate to management in both culture and natural environments. Research interests include the aquaculture of food and ornamental fish species, the enhancement of fish nutrition and physiological processes regulating commercially important traits, and the control of stress, growth, metabolism and reproduction in fish, including the delineation and regulation of hormonal signaling systems, for both aquaculture and the conservation of native fisheries.
