Large-scale efforts in genome sequencing have elucidated much of the "parts list" for thousands of species, but a general description of how genes collectively interact to produce functioning systems eludes us. We use statistical analysis of genome sequences drawn from thousands of organisms to distill out general patterns describing the organization of cellular systems.  These statistical models are then tested for their ability to explain, predict, and design cellular behaviors in the lab. In recent work, we have used statistical sequence analysis to re-wire kinase signalling pathways, and to understand genetic interactions in folate metabolism. We are particularly interested in the idea that cellular systems might be decomposed into simpler, modular building blocks.
Kim is a Moore Investigator in Data-Driven Discovery. She completed a PhD in biophysics at UC Berkeley with Dr. Tracy Handel, where she studied the computational design of protein-protein interfaces. As a postdoctoral researcher, she developed a model for the evolution of new allosteric regulation and experimentally tested the idea of allosteric "hot spots" with Dr. Rama Ranganathan (at UT Southwestern).
