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.
