Overall theme of the research program

Since moving to UC Davis in 1980, my overall objective has been to run a research group working in mathematical and theoretical biology, with a focus on ecology, evolution, and behavior and the broad goal of combining first-rate basic science with important applied questions, which Donald Stokes called Pasteur's Quadrant. My students, post-docs, and I use mathematical methods to solve problems in biological and ecological science (rather than problems in biological and ecological science to motivate mathematical studies). The tools are models (differential equations, stochastic dynamic programming and Bayesian statistical methods), experiments (currently either in Santa Cruz or in collaboration with colleagues elsewhere) and field observations. I have applied these ideas to a variety of systems, currently including insect parasitoids and tephritid fruit flies, southern ocean krill, steelhead trout, Pacific rockfish, and planaria. My students and post-docs have worked on a wide variety of species and systems including kangaroo rats and their predators, beach strawberries, sticklebacks, preying mantids, and anchovy and sardines

Winter 2017, I was Glaser Professor in the Department of Biology at Florida International University. While there, I gave five talks (in addition to one about the whaling case): Thoughts on Modeling in Biology, Ten Principles from Evolutionary Ecology Essential for Marine Conservation, State Dependent Behavioral Theory for Assessing the Population Consequences of Disturbance, The Evolutionary Ecology of Offspring Number and investment, and Invasion Biology and the Success of Social Networks

A few of other talks, given as seminars at research institutions:

The Evolutionary Ecology of Offspring Number and Size

State Dependent Life History Theory and Stem Cell Biology
