High-resolution cryo-EM of macromolecular assemblies

Our research is focused on structure and function of macromolecular assemblies using three-dimensional cryo-electron microscopy (cryoEM), combined with biochemical, biophysical and molecular biology methods. CryoEM is a powerful tool for structure determination of large protein complexes and macromolecular assemblies, and their conformational changes to provide structural snapshots along dynamic processes. Research efforts in our lab are currently directed to two areas in biology: (I) HIV pathogenesis, particularly HIV capsid assembly, maturation, and interactions with host cell factors; (II) molecular mechanisms of signal transduction in bacterial chemotaxis. We are also developing technologies to bridge the gap in single molecule imaging, by integrating optical and electron imaging methods (correlative microscopy), and working at the interface of nanotechnology and biology.
