I am interested in understanding how plants and their interactors (pollinators, seed predators, herbivores) respond to changing environments. Currently, my main research activities include studies of mating-system and floral evolution in the neotropical vine Dalechampia, and studies of the role of species interactions in structuring the spatial and temporal dynamics of communities. I am also interested in understanding how alpine plant communities respond to climate change. I study these processes in the field, in the greenhouse, and through comparative (meta-)analyses.
