Wonwoo Lee, Ph. D. 

  I received the B.S. degree from the Dept. of Mechanical Engineering, Hanyang University, Korea in 2003, and the M.S. degree from the Dept. of Information and Communications, Gwangju Institute of Science and Technology (GIST), Korea in 2004. I received his Ph.D. degree from the Dept. of Information and Mechatronics of GIST in 2012. My research interests include image-based 3D reconstruction, real-time object detection, and general-purpose computation on graphics processing units (GPGPU).
