Degrees:

1998 PhD University of California, San Francisco Biochemistry
1989 BA Haverford College Biology

Research Interests:


Light is essential for plant growth. Perhaps as a consequence, plants have an intricate set of photoreceptors and responses that they use to optimize their development and physiology to suit their light environment. We study the ways in which plants have evolved differences in their light perception and responses that allow them to thrive in different environments. We are interested in both the genetic and molecular basis of variation in light response as well as the adaptive consequences. A combination of molecular and quantitative genetics is used in Arabidopsis, Tomato, and Brassica
