Research Interests:

In my lab we are interested in evaluating the ecological and evolutionary consequences of plant-animal interactions. Particularly of interactions between plants and their pollinators. Current research in my lab aims to understand the processes and mechanisms that allow plant coexistence, flowering overlap and pollinator-sharing in diverse plant communities. We are particularly interested in determining the roles that negative (i.e. competition and heterospecific pollen transfer) and positive (i.e. facilitation) plant-plant interactions via pollinators play in the assemblage of co-flowering communities. For this we use a variety of approaches including field and greenhouse experiments as well as make use of community assembly and network theory. Plant-pollinator interactions are not just fascinating from an ecological perspective, but are also responsible for the majority of our food supply. These interactions are also crucial for the maintenance of biodiversity and are currently being threatened by changes in climate and habitat use. Overall, my research covers broad topics such as plant biology, plant-animal interactions, conservation biology, community ecology, pollination biology and floral trait evolution.
