Research Fields and Interests:
My lab has been focusing on the following aspects of biochemical research: Structure, function and activity modulation of molecular chaperones (e.g., small heat shock proteins, HdeA-a molecular chaperone for acid resistance); the biogenesis and quality control of membrane proteins (particularly the beta-barrel outer membrane proteins and the ATP synthase in Gram-negative bacteria); and the molecular mechanism of dormancy. We are currently more focused on exploring proteins in living cells by using the photo-crosslinking method based on the genetic incorporation of unnatural amino acids into proteins in a site-specific or random manner.
