She received her Bachelor’s degree from the University of California–Berkeley in Integrative Biology, and received a Master’s degree in Ecology, Evolution and Biodiversity from Pierre and Marie Curie University in Paris. She received her Ph.D. in Ecology from Pennsylvania State University focusing on ecological modeling, climate change and population dynamics. Her area of expertise is in developing quantitative tools and methods to understand the causes and consequences of species decline, and to inform conservation strategies and decision-making at the species-to-landscape scale. She has conducted research for more than 10 years in a wide variety of systems from migratory bats and butterflies to neotropical primates. At the Foundation, she leads modeling efforts to better understand the effects of restoration scenarios on the animal and plant communities of the Everglades.
