Personal profile

Research interests

Our research is aimed at understanding the basic biology of plant growth—particularly the signaling systems that regulate growth and development as well as plant responses to biological and physical stresses. Our group focuses on the application of modern biochemical analysis supplemented by metabolomics and proteomic systems biology approaches to look at complex biological processes.
