Associate Professor of Biology

Joey Davis investigates how cells maintain a delicate internal balance of assembling and dismantling their own machinery — in particular, assemblages of many molecules known as macromolecular complexes.

Research Summary

The Davis lab is working to uncover how cells construct and degrade complex molecular machines rapidly and efficiently. We apply a variety of biochemical, biophysical, and structural approaches including quantitative mass spectrometry and single particle cryo-electron microscopy to understand the detailed molecular mechanisms of these processes. Ongoing projects in the lab are focused on autophagy, an essential eukaryotic protein and organelle degradation pathway, and assembly of the ribosome, which is essential in all cells.
