About me

I’m interested in the ecological and evolutionary processes that maintain coexistence, and the effect that global change is having on these processes.

I’m currently a postdoctoral fellow at Princeton working with Jonathan Levine. My research looks at how species rapidly evolve in response to the joint pressures of climate change and competitive interactions. 

I did my PhD with Ben Gilbert at the University of Toronto, where I looked at the effects of climate change on species living in patchy habitats (metacommunities). This work showed how local species interactions and dispersal shape ecological communities, and how warming affects coexistence by altering these two processes.
