Research Interests

How do animals choose mates? What about plants? Compatible mate choice mechanisms have striking evolutionary significance in organisms across kingdoms, but in flowering plants, are less well understood. Indeed, because of their lack of mobility, flowering plants are sometimes thought to be passive and indiscriminate mates, accepting all sperm with impartiality. Empirical studies have demonstrated this not to be so. In my lab, we exploit tools available in the model plant Arabidopsis thaliana to identify genetic architectures and discrete cellular behaviors that lead to nonrandom mating in plants. The long-term goal of my lab is to fully understand the genic underpinnings of nonrandom mating in plants.
