I'm a University professor and researcher in the field of Advanced 3D printing and 3D printed sensors at Simon Fraser University (SFU), Canada. Prior to joining SFU, I was a Senior Research Scientist in Xerox Corporation (XRCC) for two years after the period of a Post-doctoral Research Associate in Massachusetts Institute of Technology for two and half years. I received BSc degree from Yonsei University in 2001 and MSc and PhD degrees from Korea Advanced Institute of Science and Technology (KAIST). I'm a senior member in IEEE and one of Associate Editors of the IEEE Transactions on Electron Devices. I love heading up to BC's mountains for the abundance of winter fun.
