B.A. Plant Biology with Honors, magna cum laude, 2000.
Bio21: Introduction to Physiology
Experimental Plant Development
Light and Life
As a global community, we rely on plants to produce food, fuel, and building materials but we know surprisingly little about the biological processes that control plant growth. Therefore I with students in my lab study the fundamental mechanisms that control plant growth at the cellular and genetic levels. All organisms (including plants!) grow to a specific shape and size that is required for their survival. The size, shape, and number of cells that make up an organism dictate the overall form of the body. The processes that determine the shape, size and quantity of cells are precisely regulated, yet sufficiently malleable so that life forms can respond and adapt to their environments. My research explores the molecular mechanisms that control plant cell growth. Specifically, I study how the microtubule cytoskeleton affects plant growth. My model system is Arabidopsis thaliana, the fruit fly, or lab rat of the plant world. My basic research has the potential to translate into advantages in food security and biofuel production.
