Research interests:

The main goal of my research group is to develop cryo-EM methodology, in combination with various biochemical, biophysical and computational approaches, to address fundamental mechanistic problems in biological complexity, with emphasis on the complex dynamics and energetics of significant biomolecular machineries at the atomic level. We are interested in the following topics in the interdisciplinary areas across cryo-electron microscopy (cryo-EM), molecular medicine, machine learning, and bioinformatics:

(1)   Developing novel cryo-EM imaging approaches and machine-learning algorithms in expanding the technical capability of biomolecular imaging to enable 4D visualization of highly dynamic and heterogeneous biomolecular complex systems at atomic resolution. We are currently focusing on 4D cryo-EM, 4D electron tomography and phase-plate imaging. We are particularly interested in innovating algorithms in manifold learning, deep learning and artificial intelligence for analyzing cryo-EM data in broadly-defined biomedical applications.

(2)   Applications of these novel imaging methods to enhance our understanding of the molecular basis for human diseases and to expedite the development of therapies and vaccines. Our current research emphasizes a mechanistic understanding of the molecular basis of neurodegenerative diseases, immune responses, and immunodeficiency. We are interested in applying this mechanistic understanding to make translational innovations in cancer immunotherapy and immunogen engineering.
