I am a freshwater community ecologist, and my research program focuses on using invasive species to answer ecological and evolutionary questions. Nonindigenous species can alter ecosystems and threaten global biodiversity, so understanding the conditions that promote invasion success and control the impacts of invaders is important for management of today’s ecosystems. Further, the addition of species to novel communities and environments provides natural experiments that are powerful tools for investigating questions in ecology and evolution. I am particularly interested in how evolution over short timescales alters the traits of species and their ecological impacts. I also study interactions between native and invasive species, especially interactions between parasites and their hosts. I am currently an assistant professor in the Fisheries and Aquatic Sciences Program at the University of Florida.
