Research Summary

Our goal is to understand, at a high level of detail, how the interaction properties of proteins are encoded in their sequences and structures. We investigate protein-protein interactions by integrating data from high throughput assays, structural modeling, and bioinformatics with biochemical and biophysical experiments. Much of our work focuses on α-helical coiled-coil proteins, Bcl-2 apoptosis-regulating proteins, and protein domains that bind to short linear motifs.
