About

I did my Ph.D. at Korea University in the Computer Vision Lab, supervised by Prof. Seungryong Kim. My PhD was focused on Computer Vision and its applications, especially in the tasks of image matching, 3D reconstruction, pose estimation and novel-view rendering. During my PhD I had the opportunity to intern in Microsft Research Asia, working with Chong Luo and Jiaolong Yang. I was also fortunate to work with Prof. Marc Pollefeys. I am one of the Google Ph.D. fellowship recipient of 2023. I am currently working as a postdoctoral researcher with Seungryong Kim at KAIST. In September 2025, I will be joining ETH Zurich as a postdoctoral fellow.
