Research

In my lab, we explore ways in which interactions among species, such as predation and competition, influence the origin and maintenance of species diversity on both ecological and evolutionary scales. My approach is mechanistic. That is, I study how traits of individuals, such as body size, life history, and behavior, influence the nature of species interactions and ultimately generate patterns in populations and communities. Furthermore, I study how these interactions shape species evolution and lineage diversification. My study systems are freshwater animal communities, and for the past several years I have explored the ecology and evolution of freshwater crustaceans in the genus Hyalella. Please visit my lab website for more information.
