H. Diessel Duan, Ph.D.
Postdoctoral fellow, Huilin Li Laboratory


Dr. H. Diessel Duan earned his B.S in chemical engineering from Jiangnan University and his Ph.D. in biochemistry from Auburn University. His graduate work focused on catalase-peroxidase (KatG), a key enzyme for bacterial pathogens to survive oxidative damage from host immune responses. He went on to study flavin-based electron bifurcation, now regarded as the third mechanism of biological energy conservation. In 2020, he joined the lab of Dr. Huilin Li as a postdoctoral fellow.


Current research focus

Investigating the mechanisms of lipid transport across biological membranes by P4 ATPase machinery.
