The Steven Laboratory seeks to elucidate structure-function-assembly relationships of macromolecular complexes by cryo-electron microscopy integrated with other approaches. Systems currently under study include viruses, cytoskeletal filaments, energy-dependent proteases, and amyloid filaments.
There are five main topics studied by the lab:
- Structural virology
- Energy-dependent proteases
- Macromolecular Complexes in Skin and Muscle
- Methodological Developments
