My research explores how evolution can occur rapidly in plant populations. Specifically, my research aims to understand (1) how evolutionary processes (hybridization, selection) and properties (mating systems, genetic diversity) affect the ecological function of plant populations (e.g., reproduction, extinction) and (2) the ecological mechanisms regulating genetic diversity, phenotypic evolution, and demography in rare and invasive plants. This leads me to work on the evolution of agricultural weeds, the conservation of rare plants and the population dynamics of native species.
