The Community Ecology of Invasions: Direct and Indirect Competitive Effects

My PhD research examined the consequences of species invasions on community dynamics.Using invasive ants as a model system, I investigated the role of direct and indirect interactions such as competition and parasitism on resident species. I further developed spatial models to understand under what conditions species can invade communities

The Community Ecology of Pathogens: Coinfection and Spatial Structuring

As a postoc, I am studying the consequences of multiple infections for virulence evolution. Using a joint experimental evolution and modeling approach, I seek to understand how coinfection dynamics shape the evolution of pathogens across different environments.

Vector behavior and infectious disease dynamics

As part of an international working group, we are investigating the role of general vector traits driving coinfection dynamics in humans, plants, and animals .
