Research Interests
Structural biology of signal transduction
Research Summary
My laboratory works towards understanding atomic-level mechanisms of signal transduction regulation. We have three primary areas of research.
- Cytokine signal transduction by the Janus kinases;
- Integrin-associated signaling cascades;
- Trp channel regulation.
Our goals are to utilize structural studies to understand the atomic-level mechanisms of signal transduction regulation, to investigate pathologic mechanisms of signal dysregulation, and to aid in drug discovery applications.
