Who am I?

I am a third year Ph.D. student in the department of Computer Science at Columbia University. I've been working as a GRA in Internet Real Time Lab under Professor Henning Schulzrinne 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 here, I co-founded Neogenius, a software startup, in Seoul, Korea and worked as a software developer and a project manager for over four years. Although my dream of early retirement didn't come true, I really enjoyed my life in those days.
I got my B.S. degree from the department of Computer Engineering at Seoul National University, Seoul, Korea in February 1997.

What am I doing?

Currently I'm working on the Next Generation 9-1-1 Project in which we have built a prototype system for an emergency call over VoIP networks. Determining a caller's location and routing the call to the proper PSAP are the most challenging part of our project. My contributions are designing and implementing psapd which is the call distributor at PSAP as a 3rd party call controller written in C++ using LIBSIPAPI in CINEMA and building the LoST server which resolves a correct PSAP URL from the caller's location and the service URN.
