Research Program Summary
My research interest is in the developmental basis of plant form and its diversification during evolution. Studies typically combine comparative developmental morphology and molecular genetics.
In particular, my work aims to understand how leaves develop, and how the molecular control of developmental processes have changed during evolution to give rise to the impressive diversity of leaf morphology that we see in nature.
Our studies concentrate on the Papaveraceae, a plant family at the very base of the large eudicot lineage of angiosperms. Understanding the genetic control of morphogenesis in basal eudicots is important for assessing evolution of development across angiosperms. Within this family, the California Poppy Eschscholzia californica has become a model plant.
Other recent projects are addressing the role of YABBY genes in the evolution of peltate leaves in Tropaeolum majus, and the role of CYCLOIDEA-like genes in shoot branching and flower symmetry.
Undergraduate and graduate students are welcome to inquire possibilities to conduct research projects in the lab. Funding may be available even when no position is advertised.
