The Department of Chemical and Systems Biology explores the molecular mechanisms that underlie cellular function and contribute to human disease. Our laboratories emphasize interdisciplinary research that spans the biomedical sciences, including signal transduction, cell cycle regulation, chromatin remodeling, protein homeostasis, metabolism, and cell differentiation. By integrating genetic technologies, biochemical and chemical tools, quantitative measurements, and computational modeling, we strive to deconstruct these complex biological systems, predict emergent behaviors, and translate these discoveries into new medical therapies.
The Chemical and Systems Biology Graduate Program trains students to explore the function of complex biological systems at a quantitative and molecular level. Research in our laboratories combines state-of-the-art approaches from chemistry, biochemistry, cell biology, genomics, computational modeling, and other disciplines to understand cellular and organismal physiology, predict emergent behaviors, and translate these discoveries into new technologies and therapies. Our faculty members are internationally renowned scientists who foster an innovative and collaborative research environment, and alumni from our home program are leaders in academics, biotech, and science policy.
Postdoctoral fellows are an integral part of the Chemical and Systems Biology community, playing active roles in its research and training activities. Fellows join the Chemical and Systems Biology Postdoctoral Program through individual laboratories, and interested applicants should contact faculty members directly.
