His main expertise is in the identification, analysis and perturbation of protein interactions. His lab is developing novel methods to dissect and inhibit interactions of modular protein domains, which involve a combination of experimental and computational methods. Other major foci of the Kim lab are roles of short linear motifs in signaling as well as effects of alternative splicing on proteins and protein interactions. Before to setting up his lab at the University of Toronto in 2009, he was a postdoctoral fellow at Yale University where he pioneered structural analyses of protein interactions networks and an associate with McKinsey & Co. He holds a Ph.D. from the Massachusetts Institute of Technology and a B.S. in Biochemistry and Physics from the University of Tuebingen.
