SAVE THE DATE! CSB Scientific Retreat, September 11-13, 2024, Asilomar Conference Grounds, Pacific Grove, CA!
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.
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.

Engineered Substrate-Specific Delta PKC Antagonists to Enhance Cardiac Therapeutics.
How are nutrients recognized by their protein sensors? How is their transport across cellular and intracellular membranes regulated? And, how is nutrient sensing integrated with other chemical signals, such as hormones, to determine cellular decisions, especially the decision: to grow or not to grow? We are a team of structural and chemical biologists aiming to answer these questions at the level of ångstroms, nanometers, and micrometers. Many proteins in these pathways are deregulated in cancer, and we are developing targeted chemical probes to modulate their activity in cells and organisms.
