Research Interests

Zooplankton ecology; population and community ecology, role of the physical environment in determining the distribution, abundance, and behavior of zooplankton, and the adaptations of organisms to their environment; trophodynamics and population ecology of marine copepods; model descriptions of population dynamics of marine organisms; individual-based modeling of bioenergetics and individual variability (feeding histroy, acclimation, energy reserves) in determining behavior, growth, development. and reproduction of crustacean zooplankton.

Current Research

Coupling of physical circulation models of ocean transport with nutrient-phytoplankton-zooplankton ecological models and individual-based models of zooplankton energetics and demography; biological-physical interactions in the pelagic and intertidal environments.
