Profile

The goal of our research is to identify the rules, chemical logic and organizational principles of metabolic networks in cells. How does metabolism function as the ultimate form of biological information flow, to drive the chemical processes required for life? To understand this, we study how some metabolites are formed, and are sensed within and between cells. We also study systems level principles of metabolic network organization, build frameworks to understand metabolic exchange between cells, and how the evolution of metabolic pathways might have determined these resource allocation strategies. Natural extensions of these studies are to understand extreme biology in model and non-model organisms. We are also using metabolic engineering of cells for regenerative biology, food, synthetic biology and environmental biotechnology.
