Research interests: "I am interested in how biological communities have responded to large-scale environmental changes in the past. I'm particularly interested in organisms' responses to the climate change that occurred during the last Glacial-Interglacial transition.

"I have always been interested in the history of life. My previous research was focused on plant community change due to precipitation and climate during the last 50,000 years. Now, in the Barnosky Lab, I'm really enthusiastic about seeing how mammal communities have responded and adapted to past environmental changes."
