  • Our work spans diverse areas related to protein folding and homeostasis, including monitoring protein folding in vivo, uncovering the mechanisms of molecular chaperones, and designing and engineering enzymes to enhance stability. In recent years, we have also explored the integration of deep learning with protein engineering.
