Chang is was a PhD student in the Network Systems Group at Princeton University, where he worked with Prof. Jennifer Rexford. He is primarily interested in designing and building novel network architecture for data centers and enterperises. In continuation of this effort, he joined Microsoft (Windows Azure) and is leading network-virtualization projects for cloud data centers. His new homepage at Microsoft is here. He had extended internships in research groups at AT&T Research and Microsoft Research. Before joining the PhD program at Princeton, he worked as a researcher for ETRI, a government-funded R&D institute in Korea specializing telecommunications. He also worked shortly as a technical consultant for Samsung Networks Inc. which manages Samsung's global corporate network. Chang received BSE and MSE in computer engineering from Seoul National University.

If you're interested in trying out or building upon the SEATTLE prototype switch, please contact me. I'll be happy to support exciting follow-up or collaboration work on that.

My research interests span over designing, building, and deploying architectural solutions that facilitate operation and management of large-scale networks and networked services. I particularly enjoy working on this broad topic with regard to fast-growing network edges: enterprise/campus networks, data-center networks, virtual private networks, any general networks in less developed areas, etc.
