I joined NASA's Jet Propulsion Laboratory at Caltech on October 2011. Prior to that, I completed my national duty at ETRI, Korea, working as a research scientist. I received my Ph.D. from the University of Texas at Austin on August 2008. I worked as a member of Prof. J. K. Aggarwal's research group, Computer and Vision Research Center. I obtained the B. S. degree from the Division of Computer Science at Korea Advanced Institute of Science and Technology (KAIST) on August 2004.
