RESEARCH

   My research program reflects my background and expertise in
   theoretical ecology, simulation modeling, and complex systems. I
   have applied this expertise to research questions pertaining to the
   conservation of endangered species, the control of invasive species,
   foraging and movement behavior, and habitat selection. My students
   and I use a variety of contemporary modeling tools and    methodologies including GIS-based landscape analysis, spatially-
   explicit stochastic simulation, cellular automata, and individual-based
   models, as well as more traditional tools such as matrix population
   models.

   I have also been involved in making people within my discipline
   aware of the relevance and applicability of the risk assessment
   paradigm. Many people in the fields of ecology and natural resource
   management feel strongly that science needs to be integrated
   thoroughly into environmental policy; many of those same people
   seem to be unaware that this is a problem which has already been
   solved. Ecological risk assessment provides an explicit and well-
   understood means for bringing science to bear on policy issues.
