Research Interests

I am broadly interested in examining species interactions in agricultural landscapes in the context of a changing climate. My research often focuses on questions related to competition and predation in ant and bee communities and how these interactions are affected by species composition, disease, nutrient limitation and seasonality. These interactions often have important implications for agriculture especially related to pest suppression, pollination, crop health and yield.
