Research Abstract:

Plants are amazing chemists capable of generating an array of small molecules with different biological effects. Our research seeks to broadly understand how environmental changes re-model biochemical pathways in plants at the molecular, cellular, and organism levels with the aim of engineering these systems to address agricultural and environmental problems. Current work in the lab employs a combination of x-ray crystallography, enzymology, molecular biology, proteomics, and plant biology to address the following questions: What are the biochemical networks involved in responding to specific environmental stresses and how are they organized? How do different biochemical mechanisms regulate these pathways? What are the connective systems that allow for integration and cross-talk between metabolic pathways in plants? Can we re-engineer plant pathways and the links between different control systems to improve plant performance under environmental stresses?
