(1). Community ecology of disease: We are studying the influence of infectious disease on population dynamics and community interactions. Our work also focuses on the determinants of spatial and temporal dynamics of bacterial and fungal epidemics in Daphnia. This work relies on combination of community ecology, physical limnology, and epidemiological modeling.
(2). Food web stoichiometry: We are developing and testing theory focused around the intersection of ecological stoichiometry and food webs. The stoichiometric approach explores the consequences in mismatches in the elemental composition of grazers and plants. We use stoichiometric models to understand competition and coexistence among grazers, new roles for inedible producers in systems, plant-herbivore dynamics, and strength of trophic cascades.
