Research Interests
Genetic Basis for Adaptations in Plants
Plant evolution and population biology are the major topics investigated by myself and my students. We are using Y chromosome molecular markers to determine how many male individuals have contributed to specific populations. These markers also allow us to track both the survival and the movement of individuals within and between populations. Also, we are investigating competitive interactions between pollen grains as they develop within the anther, between pollen tubes growing the style, and what influence these interactions have on the resulting sporophytic generation. The basic approach in this lab is to employ molecular methods to investigate topics of whole plant biology.
