I am an evolutionary biologist with a focus on plant breeding system evolution. Plants exhibit a wide range of breeding systems across families, species and populations. I am interested in how processes within and among populations interact to maintain breeding system polymorphisms. For this research, I use formal and informal models, field studies, genetic markers, and greenhouse experiments.
