Yuan He Assistant Professor

Research Summary:

The He lab is interested in understanding the molecular mechanisms by which large, multi-subunit complexes engage in DNA-centric processes using cryo-electron microscopy (cryo-EM) combined with image processing and other biophysical and quantitative approaches. We focus on two main topics: (1) how eukaryotic gene transcription is regulated at different stages, and (2) how various types of DNA damage are repaired and why deficiencies in these repair pathways lead to pathology of cancer predisposition or accelerated aging.
