Professor in the Molecular and Cellular Biology Graduate Program

We use biochemical, molecular, and genetic strategies to study how plants grow and respond to changes in their environment. Our research is focused on the roles played by the plant hormones ethylene and cytokinin, and is relevant to solving real-world agricultural problems, such as the control of ripening and senescence.
