My research centers on theoretical and applied population and community dynamics, risk assessment, ecosystem modeling and statistical assessment and management of marine fishery ecosystems.  A particularly novel aspect involves development of large-scale dynamic ocean ecosystem models to assess sustainability risks of multispecies coral reef and coastal gamefish resources from exploitation and environmental changes.  In support of my analytical approach, I design and conduct fishery-independent field assessment studies on multispecies coral reef fish communities, deepwater snappers, pink shrimp, bonefish, tarpon, billfishes and tunas in the Atlantic and Pacific Oceans and Caribbean Sea that are focused on the biophysical linkages reflected in ontogenetic migratory behaviors and response to biophysical conditions to better quantify optimal sampling surveys and define underlying empirical mechanisms in population dynamics and spatial grouping.  I am also interested in exploring means of taking structure into account in population and community models of coastal ocean ecosystems both to understand the forces driving recruitment variability and to improve resource prediction and the prospects for sustainability.
