Welcome! I am a postdoctoral research fellow working with Dan Rabosky in the Department of Ecology and Evolutionary Biology and Museum of Zoology at the University of Michigan. I am broadly interested in ecology, evolution, and conservation of biodiversity. My current research seeks to understand why species live at different elevations and how they respond to environmental change. Most of my work focuses on amphibians and reptiles distributed in the Andes-Amazon region, and I integrate different types of data to examine divergence in species’ thermal physiology and eco-morphology along elevational gradients.
