Research Interests
I investigate ecological interactions among living and recently extinct animals (including humans) using stable isotope biogeochemistry. My interests include niche partitioning, conservation biology, and Quaternary paleoecology. I am particularly interested in the causes and consequences of recent extinctions, and the ecological repercussions of habitat fragmentation and degradation.
Current Research Projects
•Disentangling the impacts of recent human activities and climate change in Madagascar.
•Investigating changes in diet and mobility patterns of extinct and extant North American megafauna.
•Reconstructing the foraging ecology and extinction chronology of now-extinct rodents in Hispaniola.
•Evaluating the isotopic effects of digestion in predatory birds.
