  • Dr. Jennifer Nelson (2006): Jenn studied how different predator behaviors affect the stability properties of a predator-prey model system, namely the Rosenzweig-Macarthur model. She also examined predator-prey dynamics when the prey interact with a chemo-attractant.

    •  
  • Dr. Curtis Smith (2006): Curtis entered the lab Fall 2001 through the University Program in Ecology. He worked on spatial models of exploiter-mutualism systems, and more general activator-inhibitor systems, to examine the evolutionary stability of dispersal in pattern-forming systems. He also reexamined data on the California sea otter, putting forth a new understanding of it's apparent asymmetric dispersal.

    •  
  • Dr. Yu Zhang (2004): Yu worked on general plant mating system models. In particular, she examined models of heterostyly, an observed flower dimorphism in which the style length varies between plants. This dimorphism comes in a variety of flavors including distyly, tristyly, and enantiostyly. Also involved is self compatibility and self incompatibility. She also studied an ecological competition model for dioecy. Presently she's pursuing studies in economic game theory at Texas A&M.

    •  
  • Dr. Michael Gilchrist (2001; with Janis Antonovics): Mike's main project was formulating mechanistic, within-host disease models and using these to examine host and parasite evolution. He also worked on scaling these detailed models up to the level of between-host model formulations. Mike also spent a semester at Lake Forest College, working with Anne Houde, measuring the transmission rate between all combinations of male and female guppies. Mike is now at the University of Tennessee - Knoxville.

    •  
  • Dr. Aaron Ashih (Math 2001; coadvised with David Schaeffer): Aaron worked on a variety of mathematical biology problems. One was a one-species, two-sex model that incorporated a variety of mating processes, including coupling and gestation. Mating models typically have an Allee effect, mean that a finite population density is needed for a positive population growth rate. His work demonstrated that details of the mating process seriously affect this threshold density. Other things Aaron work was the analysis of stochastic, spatial individual-based models.
