Jun-Ho Choi

I am a postdoctoral researcher at MCML Group (led by Prof. Jong-Seok Lee), Yonsei University, Korea. I completed my PhD degree in Engineering at School of Integrated Technology, Yonsei University, Korea, where I was advised by Prof. Jong-Seok Lee. My research interests include multi-modal deep learning, adversarial attacks, image super-resolution, and so on.

I am also making some mobile and web applications under the name Daram Studio.
