Expert on the development and use of cryo-electron microscopy (cryo-EM) as applied to viruses, bacteria, and human cells.
- How do bacteria move and make contact? Bacteria use special appendages, pili and flagella, to move and connect with surfaces.
- How do viruses, like HIV, assemble? Viruses replicate within a host cell and essential components are transported to sites of assembly where they are released.
- What is cryo-EM? Cryo-EM is a structural biology technique where samples (bacteria, viruses, etc) are embedded in an ice layer and imaged by electron microscopes.
