    Collapse Overview 
    Collapse overview
    My research program involves synergistic studies of protein folding and design, protein-RNA interactions, phosphorylation, signaling, and function 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 lab employs a range of experimental and computational methods including hydrogen exchange (HX), NMR, small-angle X-ray scattering (SAXS), rapid mixing methods, mass spectrometry, molecular dynamics and home-grown coarse-grain folding simulations and modeling. I am a very a strong believer in collaboration, having co-mentored over twenty students and post-doctoral fellows who produce over 60 papers in the last 20 years. I have a history of developing multi-approaches to bear on a problem. Since my Ph.D. in low temperature physics in 1989, I have entered many different areas, including delineating protein and RNA folding pathways and denatured states, de novo structure prediction, and the design of light-sensitive allosteric proteins.
