Current Research Interests:
The research projects in my group are focused on method development and applications of cryo-EM to various biological systems. Current application projects include 1) structural basis of assembly and infection mechanism of dsDNA tailed bacteriophages and human noroviruses; 2) structural studies of protein complexes involved in epigenetics, signal transduction, and protein degradation; 3) structural based discovery of antivirals and cancer drugs. We are also interested in developing methods to improve all aspects of cryo-EM techniques including image processing algorithms, high-performance computing, data collection automation, and sample preparation. Current projects include 1) virtual reality-augmented cryo-EM training system (CryoVR); 2) genetic, biochemical, and physical approaches to stabilize protein complexes and to reduce flexibility to allow high-resolution 3-D reconstruction; 3) computational algorithm and software to process cryo-EM 2-D images and to reconstruct 3-D structures at near-atomic resolutions (1.5-4 Angstrom)
