My research focuses on population models, usually based on matrices, for plants, animals, and humans.  I am interested in stochastic processes in demography, including individual stochasticity (random outcomes of individual lives, affecting indices such as longevity), demographic stochasticity (random growth of populations generated by the stochastic outcomes of survival and reproduction), and environmental stochasticity (fluctuations in the vital rates that affect all members of the population). I study both basic theory and the application of that theory, especially to evolutionary questions and to environmental questions related to climate change.
