RESEARCH
Synopsis:
My graduate students and I work in two areas: High-resolution protein NMR studies in living cells. Biophysics of tardigrade dessication-tolerance proteins.
works in three areas:
High-resolution protein NMR studies in living cells.
Oxidative damage to 伪-synuclein, a key protein in Parkinson’s disease.
Pressure perturbation calorimetry of peptides and proteins.
Summary:
My goal is to understand the chemistry of proteins as it occurs in living cells. This knowledge is fundamentally important and essential for ensuring that simple, inexpensive in vitro experiments can be used with confidence to diagnose and treat human disease. My lab has pioneered the study of both globular and disordered proteins under actual biologically relevant conditions both in vitro and in cells. We do this by developing innovative techniques to measure protein stability and diffusion in the presence of huge amounts of solutes that interfere with standard measurement techniques.
