Evolution and Population Genetics

Most of our work involves the study of plant reproductive systems to address broader evolutionary issues. We are studying invasive species as models for the evolution of geographic range expansion. We also study how evolution is influenced by the fact that populations are distributed in space (population structure). Several projects focus on how selection at one level or organization subsumes, or is subsumed by, selection at higher levels or organization...so-called "levels of selection". This has led us into studies of genetic conflict such as epidemics of selfish genes within natural populations and mitochondrial diseases that result from the accumulation of parasitic organelles within cells.

Students generally develop their own research programs so the research going on in the lab is diverse. Follow the research links for details of our projects.

Our work involves a wide variety of methods: phylogenetics & molecular population genetics, field experiments, greenhouse experiments & crossing studies, theory.
