Profile Introduction

Physiological ecology, growth, and reproduction of marine invertebrates, especially crustaceans.

Degrees

1978 PhD Biology University of California, Los Angeles
1973 BA Zoology University of California, Berkeley

Research Contribution

My laboratory is broadly concerned with the mechanisms of development and the physiological ecology of marine and other invertebrates, especially those mechanisms involving hormonal and pheromonal cues. We are interested in the integration of control mechanisms from the organismal and the community level down to the cellular basis of gene expression. Our current focus is on the regulation of molting and growth in decapod crustaceans. Our research combines a blend of both applied aquaculture and basic research into invertebrate behavior, physiology, and cell biology.
