The research in An lab centers around protein degradation processes in health and disease. We investigate protein degradation processes using chemical biology tools and unbiased proteomic approaches to discover previously unknown degradational pathways and molecular mechanisms. Specific research areas include 1) developing innovative chemical, biological, and proteomic tools to help advance protein degradation research, 2) identifying protein degradation pathways altered explicitly in disease and employing this information to develop small molecule probes with therapeutic potential, and 3) elucidating the fundamental role of ribosomal proteins and ribosome homeostasis using protein-degradation and chemical proteomics tools. Multidisciplinary and quantitative approaches are central to our research in addressing the questions mentioned above.

Disclosures
Doctors and faculty members often work with pharmaceutical, device, biotechnology, and life sciences companies, and other organizations outside of MSK, to find safe and effective cancer treatments, to improve patient care, and to educate the health care community.
MSK requires doctors and faculty members to report (“disclose”) the relationships and financial interests they have with external entities. As a commitment to transparency with our community, we make that information available to the public.
Heeseon An discloses the following relationships and financial interests:
