Sr. Museum Scientist (Vertebrate Collections)

Her research: "My research program is centered around understanding the pattern and process of change in the continental biota during warm intervals in the past. This could help us evaluate how long-term climate change may alter the Earth's biota in the future."

Burning questions: "How does climate change affect diversity? Do mammals and reptiles respond differently to climate change? What aspects of the biology and ecology of different taxa make them respond differently to climate change?"

Fossils that particularly interest her: "Fossil mammals and reptiles (principally turtles) from the Late Cretaceous and early Paleogene (approximately 70-30 million years ago). For the past ten years, I have maintained an active field program in the Greater Green River Basin of southwestern Wyoming, where the rocks preserve fossil mammals and reptiles from approximately 53 to 50 million years in age."
