研究领域

Molecular basis of plant development and evolution of development. Research in my lab focuses on the genetic and molecular factors that govern the development and evolution of ovules, the precursors to seeds. We study development primarily using Arabidopsis thaliana as a model system, but use a variety of other plants to study the evolution of ovule development.
