I am a PhD student in Visual Computing Lab. at KAIST. My current advisor is professor Min H. Kim. Before joining VCLAB, I obtained my master degree under the advisory of professor Yu-Wing Tai, also in School of Computing, KAIST .

My research interests are overall image processing, computer vision and machine learning, and computer graphics. In particular, I am interested in low-level computer vision problems including image super-resolution, image matting, HDR imaging, hyperspectral imaging, and other image reconstruction methods. I am also attracted by representation learning, generative models, and deep neural networks.
