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.
