RESEARCH INTERESTS
One of my current interests is in developing tools for short and long-term selection (sensitivity/elasticity) in stage-structured populations living in varying environments: how does short-term effect of changes in a trait/vital rate relates to long-term selection? what are the management implications? A related problem of interest is to estimate sensitivities of population growth rate from demographic data. I also work on the effects of temporal autocorrelation in environments on population growth and extinction. I use mathematical models and empirical data to address these questions.
While above research mainly involves one-sex (usually female) models there is growing interest in using two-sex (both female & male) models to address many evolutionary and ecological issues. Of particular interest is the role of individual behavior on population performance and extinction. Unlike usual linear PVA models two-sex models are non-linear and may need different tools. I am interested in developing theoretical methods to analyze two-sex models and the role of behavior therein.
