Research Interests

The Eukaryotic DNA Replication Structure and Dynamics Group focuses on the study of the structures and functions of the eukaryotic DNA replication machinery. We purify endogenous macromolecular DNA replication complexes at different stages of assembly from yeast cells and build atomic models of their structures based on high resolution CryoEM. This project is carried out in collaboration with the CryoEM group led by Professor Ning Gao at Tsinghua University. We also study the subcellular organization of the replication machineries within the nucleus during different stages of the cell division cycle using superresolution microscopy (STORM) and SIM lattice light sheet. This project is made possible by microscopes custom-built by our local experts, Professor Shengwang Du and Mr. Zhou Teng in the Physics Department.
