Overview:
Our laboratory uses mass spectrometry-based proteomics to investigate cellular processes related to protein homeostasis. We study the mechanisms of cellular protein folding, degradation and repair from a global perspective. We also investigate how these processes are affected by disease and aging. Current research areas include:
- development of proteomic methodologies for analysis of protein folding and degradation
- uncovering the mechanism of selectivity in macroautophagy
- determining the cellular basis of toxicity of prion aggregates
- understanding the relationship between protein turnover and aging
