Research Overview

Our laboratory studies the mechanisms of protein folding and degradation within cells. We investigate how cells maintain a balance between these two processes, and how this homeostasis is affected by disease and aging. The projects in the lab draw on a number of disciplines including protein biochemistry, proteomics and computational biology. Current research areas include:

• development of proteomic methodologies for global analysis of cellular protein degradation
• uncovering the mechanism of selectivity in macroautophagy
• analysis of the kinetics and efficiency of cellular protein folding
• mechanistic studies of prion aggregate formation and characterization of novel anti-prion compounds
