Lucas Yunkyu Lee

I'm studying computer science at POSTECH, Korea. My passion lies in the intersection between research, development, and design.

My interests include programming languages and 3D computer vision. I'm currently undergoing a research internship on floating-point computations at the POSTECH Foundations of Programming & Computing Lab.
