Before attending Carnegie Mellon University, I received a B.S. in industrial design at Korea Advanced Institute of Science and Technology (KAIST). I did an internship at Philips Design in Paris, France, where I experienced creative practices in diverse disciplines. After graduation, I worked on an intelligent agent application for a mobile phone and an autonomous home robot at SK Telecom in Korea.
