Bio 

Changho Suh is an Ewon Assistant Professor in the Department of Electrical Engineering at Korea Advanced Institute of Science and Technology (KAIST) since 2012. He received the B.S. and M.S. degrees in Electrical Engineering from KAIST in 2000 and 2002 respectively, and the Ph.D. degree in Electrical Engineering and Computer Sciences from UC-Berkeley in 2011. From 2011 to 2012, he was a postdoctoral associate at the Research Laboratory of Electronics in MIT. From 2002 to 2006, he had been with the Telecommunication R&D Center, Samsung Electronics.
Dr. Suh received the 2013 Stephen O. Rice Prize from the IEEE Communications Society, the David J. Sakrison Memorial Prize (top research award in the Department) from the UC-Berkeley EECS Department in 2011, and the Best Student Paper Award of the IEEE International Symposium on Information Theory in 2009. He was also awarded the Vodafone U.S. Foundation Fellowship in 2006 and 2007, and the Kwanjeong Educational Foundation Fellowship in 2009.

Research Interests

My research interests center on the information sciences and systems. Particularly I am interested in the high-dimensional data regime and seek to address the following issues: (1) how to fast communicate; (2) how to efficiently store; (3) how to extract meaningful information from large data sets. My work borrows from tools of information theory, coding theory, and machine learning. 

Ph.D. Dissertation

Feedback and Interference Alignment in Networks, University of California at Berkeley, Sep. 2011 (talk slides)
