I am a Ph.D. candidate in the department of Computer Science at Columbia University. My advisor is Professor Henning Schulzrinne. I've been working at Internet Real Time Lab since Summer 2005 when I was a M.S. student. I got my M.S. degree from the department of Computer Science at Columbia University in February 2006.
Before coming to New York, I co-founded Neogenius, a software start-up in Seoul, Korea, and worked as a software developer and a project manager for over four years. I learned many lessons from this experience, such as how to realize an early stage idea, how to lead people, and how to manage a company.
I got my B.S. degree from the department of Computer Engineering at Seoul National University, Seoul, Korea, in February 1997.
