My research centers on theoretical and applied population and
community dynamics, and statistical assessment and management of
tropical marine fishery ecosystems. A particularly unique
aspect is the development of large-scale spatial coupled
biophysical ecosystem simulation models to assess the response of
multispecies fisheries to exploitation and environmental
changes. Requirements for fishery management have
fundamentally changed so that fruitful areas of research now
transcend the bounds of traditional assessment theory and new
approaches must be explored. The fishery management system is a
new approach to integrate quantitative techniques in population
dynamics, sampling design, fish stock assessment, operations
research, biometrics, numerical modeling, scientific
visualization, and management science in a computer- based expert
decision support system to provide cost-effective high-precision
fish stock assessments and short-term fishery forecasts. In
support of my analytical approach, I conduct regional
fishery-independent field assessment studies on multispecies
coral reef fish communities, pink shrimp, bonefish, tarpon,
billfishes and tunas that are focused on the biophysical linkages
reflected in fish ontogenetic migratory behaviors 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 and building spatially-explicit
coupled biological-physical models of coastal ocean ecosystems
both to understand the forces driving recruitment variability and
to improve resource prediction and the prospects for
