About me

Senior Researcher and PI for research group  Protein degradation pathways at the Department of Physiology and Pharmacology

Research description

The fundamental cellular processes we are focusing on are the two major mechanisms by which cells degrade proteins: the ubiquitin- proteasome system (UPS) and the autophagy-lysosome pathways. Our aim is to understand the complexity of various degradation systems and its explicit interactions and mechanisms, with the ultimate goal to understanding how pathogenic proteins can be eliminated from the cells. In particular our research focuses on degradation of oncogenic protein in relation to cancer biology.

Currently, our main focus is on the following overarching projects:

1. The regulation, function and target(s) of DUBs in cancer.

2. The role of Chaperone-mediated Autophagy in cancer.

3. Dissecting the mechanism of oncogenic cargo selectivity.
