Our Team

Sangkook Choi joined Comscope in early 2016. He is in charge of developing GW+DMFT software together with Patrick Sémon. His research interests are diagrammatic extensions of dynamical mean field theory, their combination with first-principles methods, and the application to real materials. Sangkook Choi received his Ph.D in 2013 from the University of California at Berkeley where he worked on electronic structure of weakly correlated materials in various dimensions within GW approximation.
