Electron cryomicroscopy (cryo-EM) is an emerging technique for solving structures of large macromolecular machines. It does not require crystalline order for the studied specimens. This unique capability makes cryo-EM extremely valuable in imaging and solving the structures and the dynamics of macromolecular machines.

We use cryo-EM to study the assembly, maturation, and infection mechanism of viruses including dsDNA tailed bacteriophages and noroviruses. We are also interested in the development of cryo-EM techniques including image processing algorithms, high performance computing, data collection automation, and sample preparation. The technical advances will help push cryo-EM towards near atomic resolution (2-4 Angstrom) single particle 3-D reconstructions and tomographic 3-D reconstructions, and to ultimately transform the current laborious cryo-EM technique with steep learning curve into an easily accessible and high throughput tool at the disposal of any biologist.
