About me

I’m interested in the ecological and evolutionary processes that maintain biodiversity, and the effect that global change is having on these processes. I’m currently a postdoctoral fellow in Jonathan Levine‘s group at Princeton, conducting field experiments with fruit flies to understand how species’ rapid evolutionary responses to competition and climate.

In January 2021 I’ll be starting as a Biodiversity Postdoctoral Fellow at UBC, working with Sally Otto and Mary O’Connor

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 that live in patchy habitats.
