Research Interests

Biomedical research today is conducted largely in the context of an established paradigm that is fundamentally reductionist in nature. Yet, despite the enormous success of this approach, it is increasingly clear that discrete biological function and the astounding complexity of living systems cannot be understood by studying individual molecules. Instead, most biological characteristics arise from complex interactions among the cell's numerous molecular constituents. Thus, a key challenge for 21st century biology is to understand the structure and the dynamics of the complex intracellular web of interactions among the various types of molecules that contribute to the function and the physical entity of a living cell. Together with our collaborators, our laboratory focuses on the understanding of the system-level organization of cellular metabolism, and how environmental cues are processed through regulatory pathways leading to rearranged metabolic activities. In the long run, we are also interested in applying this knowledge to improved disease diagnosis and treatment.
