Biographical Sketch

Junghoo Cho is a professor in the Department of Computer Science at University of California, Los Angeles. He received a Ph.D. degree in Computer Science from Stanford University and a B.S. degree in physics from Seoul National University. His main research interests are in the study of the evolution, management, retrieval and mining of information on the World-Wide Web. He publishes research papers in major international journals and conference proceedings. He serves on program committees of top international conferences, including SIGMOD, VLDB and WWW. He is a recipient of the 10-Year Best-Paper Award at VLDB 2010, NSF CAREER Award, IBM Faculty Award, Okawa Research Award and Northrop Grunmann Excellence in Teaching Award.

Research Interests

The primary goal of my research is to make it truly easy for people to share, access and understand large-scale digital information. In particular, my research focuses on analyzing a large amount of information generated by users, so that we can deliver the most up-to-date, high-quality, relevant information to users. This is pursued in three different directions: (1) experimentally collecting and analyzing real-world data to gain a better insight on what the real-world is like, (2) mining the collected data to discover interesting patterns behind it, so that the discovered patterns can be used for other applications, such as recommendation systems and search engines and (3) build new algorithms and mechanisms that can help systems to deliver most up-to-date and high-quality information to interested users.
