Research Interests

I am interested in processes driving the structure and dynamics of ecosystems. My research project focuses on the role of individual species in food web stability. I use fully resolved quantitative galler-parasitoid food webs, which are manipulated and monitored in the field, to investigate the effects of species abundance and spatial distribution on food web structure. I am also interested in the role played by non-trophic interactions in maintaining ecological communities.
