RESEARCH

Synopsis:

My students and I use the formalisms of equilibrium thermodynamics and the tools of molecular biology and biophysics to understand the structure, stability, and function of globular and intrinsically-disordered proteins in physiologically relevant environments.

Pielak lab works in three areas:
High-resolution protein NMR studies in living cells.
Oxidative damage to α-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.
