My research program involves synergistic studies of proteinfolding, function and design, with both experimental and computational components. The research is based on the premise that rigorous and innovative studies of basic processes have broad implications in many areas of biological research. My experimental experience in protein folding, design, modeling, and biophysical methods provides an enormous benefit to our computational studies which heavily rely on the use of fundamental principles of protein folding.

My group is involved in many areas include delineating protein folding pathways, de novo structure prediction, design of light-triggered allosteric proteins, and membrane protein folding. My lab employs a range of experimental and computational methods including NMR, small-angle X-ray scattering, rapid mixing methods, hydrogen exchange, molecular dynamics and coarse-grain folding simulations. I am a very a strong believer in collaboration, having co-mentored 15+ students and post-doctoral fellows who produced 30+ papers in the last 10 years
