Research Interests

Conservation Biology and Endangered Species Biology  - My lab is interested in understanding causes of species rareness, particularly with regard to reproductive biology. Our work includes relating life history traits and pollination ecology to genetic variability of rare species. We are also interested in reintroduction as a potential recovery measure.
