Chang Sun received his Ph.D. in biochemistry from the University of Illinois in 2016, under the supervision of Colin A. Wraight and Robert B. Gennis. He joined the Theoretical and Computational Biophysics Group as a post-doctoral researcher in 2017. 


Robert L. Switzer Award for Teaching                                                                                           2014
Scholarship of Hui-Chun Chin and Tsung-Dao Lee Chinese Undergraduate Research Endowment       2010
Excellent student leader of Fudan University                                                                                 2008


Chang is interested in studying membrane protein with a combination of experimental and computational methods. More specifically, he focuses on the transmembrane protein complexes involved in the bioenergetics, such as photosynthesis and respiration. The applied techniques include electron paramagnetic resonance, optical spectroscopy, crystallography, cryo-EM and molecular dynamics.
