Intrigued by the myriad of function protein can possess, Chang Sun pursued a Ph.D. in biochemistry at UIUC. He had worked with a variety of bioenergetically important membrane proteins such as photosynthetic reaction center and bo3 ubiquinol oxidase during his graduate training by Colin A. Wraight and Robert B. Gennis. Specifically, he had studied how the protein matrix can tune the property of intermediate states of cofactors during catalytic cycle using pulsed electron magnetic resonance spectroscopy. As a result, he realized the important role of protein structures in dictating their corresponding biological functions. After receiving his doctorate degree in 2016, he became interested in structure determination of membrane proteins using cryo-EM and started to collaborate with John Rubinstein's group in University of Toronto. In 2017, he joined Emad Tajkhorshid's research group and had been focusing on modeling atomic structure from the cryo-EM density maps. He is also interested in using molecular dynamics simulation to better understand protein functions.
