Sung Ryul Eric Yang
Sung Ryul Eric Yang (S.-R. Eric Yang) is a theoretical condensed matter physicist. He is a full professor in the Department of Physics of Korea University.

Education 
Yang earned his Candidate of Science from the University of Copenhagen in 1982 under supervision of Henrik Smith, who is a co-author of the book Bose–Einstein Condensation in Dilute Gases (Cambridge University Press, 2008). He attended University of California, San Diego, from which he obtained a PhD degree in physics in 1986 under the supervision of Lu Jeu Sham.

Academic career 
After receiving his PhD, Yang worked as a postdoctoral researcher at the University of Maryland from 1986 to 1987. He then worked as a research officer at the National Research Council of Canada from 1987 to 1995. In 1995, Yang joined the faculty of the Department of Physics at Korea University as an associate professor and in 2000, he became full professor. He was the condensed matter coordinator at Asia Pacific Center of Theoretical Physics (APCTP) during its establishment period. 

His research interests include quantum Hall edge reconstruction, many-body physics and its interplay with disorder. He showed, in collaboration with Allan H. MacDonald, that electron interaction effects do not change the critical properties of the integer quantum Hall plateau transitions. In recent years, Yang's research focuses on topological order of disordered graphene zigzag nanoribbons. He showed that disordered interacting graphene zigzag nanoribbons is a new topologically ordered insulator with semionic  fractional charges.

Textbook 
In 2023, Yang published a graduate textbook titled Topologically Ordered Zigzag Nanoribbon: e/2 Fractionally Charged Anyons and Spin-Charge Separation (World Scientific). The book has been reviewed by Philip Kim.

Personal life 

From the age of 12, he has lived in various countries including Vietnam, Mexico, Denmark, the USA, and Canada. Denmark is where he spent the majority of his adolescent years. With a multicultural background, he prefers not to be confined to any particular cultural identity. Currently married to a Korean, he has two daughters who reside overseas. 

Yang is a passionate mountaineer, he finds joy in climbing, trekking, and camping in remote and challenging locations. His ultimate aspiration is to conquer sport climbing routes above 5.12c grades.
