I am a population biologist by training, thus my lab focuses on both the ecological and genetic factors responsible for a population’s persistence or demise. In this context the major theme in my lab is on the ecology and evolution of reproductive systems in nature. Topics we investigate include plant mating system evolution, plant-pollinator interactions including both pollinators and herbivores, demography of populations, and the role inbreeding and phenotypic plasticity play in the evolution of plant populations. Research conducted in my lab also directly relates to the need for baseline data that may be utilized to help form successful conservation and restoration management plans for threatened taxa.
