I am generally interested in evolutionarily based questions concerning various aspects of flowering plant reproduction from both ecological and genetic perspectives. At a more general level, my research focuses on understanding selective forces in natural populations and the extent to which adaptation is slowed or prevented by genetic constraints.

My recent and current research revolves around the dioecious plant species Silene latifolia.

Past research includes: (1) an investigation of the forces that select for unisexuality rather than hermaphroditism, and how this affects other plant traits, (2) the evolution of sexual dimorphism given underlying genetic correlations, (3) pollen competition, (4) how flower size and number can affect plant fitness, (5) inbreeding and inbreeding depression, (6) a multitude of questions on gynodioecious species, including the maintenance of females and the cost of restoration, and (7) reproductive isolation.
