Fan Lab focuses on interdisciplinary approaches, leveraging technical strengths to develop novel cryo-EM imaging technologies, as well as efficient sample preparation and data processing methods. The group aims to establish a platform for in situ structural and functional analysis of membrane proteins within native membrane systems. Utilizing this platform, the group will conduct high-efficiency in situ studies of complex biomembrane environments, analyzing the spatial conformations, interaction networks, and multiscale organizational patterns of key macromolecules. This work will explore the coupling and regulatory mechanisms between biomembrane systems, providing a theoretical foundation for disease intervention.
