Research Interests

I am broadly interested in the effects of anthropogenic landscape changes on biodiversity. Specifically, I attempt to understand:
(1) how habitat fragmentation affects the demographic and genetic processes of plant populations
(2) how landscape composition shapes the outcome of plant-animal interactions such as pollination, frugivory and seed dispersal
