I am fascinated by the diversity of shape and form present in flowering plants. Research in my lab is focused on understanding the molecular underpinnings of this diversity – both how it develops and how it evolves. We use the tools and techniques of both evolutionary and developmental biology to uncover the genetic networks underlying plant development, as well as to assess how these networks have changed through the course of evolution. Right now, we're leveraging the genetic systems available in the grasses to assess the function, across evolutionary time, of variable protein-protein interactions in floral development.
