About me

I’m a community ecologist, currently working as a postdoctoral fellow in Jonathan Levine‘s group at Princeton University. I’m interested in the ecological and evolutionary processes that maintain diversity, and the effect that global change is having on these processes. 

For my postdoc, I’m conducting field experiments with fruit flies to understand how species rapidly evolve in response to the joint pressures of competition and climate. During my PhD working with Ben Gilbert at the University of Toronto, I used the insects that specialize on milkweed plants to understand the effects of climate change on species living in patchy habitats (metacommunities).
