Biographical Sketch

I study the demography and life histories of long-lived vertebrates. Our goal is to understand how natural and human-caused  environmental variation influences the vital rates of survival and fecundity and affect population stability. The cornerstone of our research is long-term mark-recapture applied in an empirical context to study ecological, evolutionary, and conservation questions. We also engage in environmental education and outreach through the TERP (Terrapin Education and Research Partnership) where we integrate K-12 environmental education and literacy with conservation science to both enhance awareness and evaluate the effectiveness of conservation / management strategies.
