Research in my lab examines the processes that promote and limit adaptive evolution at the phenotypic and molecular level. I have been particularly interested in how broad-scale spatial and temporal variation in ecological factors influence phenotypic evolution and molecular evolution of genes that underlie ecologically-important traits. I am currently pursuing research on topics including: (1) the evolution of species’ geographic ranges including studies ranging from field ecology to molecular evolutionary genetics, (2) evolution and ecology of reproductive isolation between recently diverged plant taxa, (3) mating system and floral evolution, and (4) evolution of endemism in temperate forest herbs and the conservation of narrowly distributed plant species. Outside of these projects, I maintain research on the ecology and evolution of species interactions including plant-pollinator and plant-herbivore interactions
