Hello!
I'm Yoohyuk
I'm Yoohyuk (Paul), an undergraduate student at Johns Hopkins University (Baltimore, MD, USA) studying computer science.
I love traveling to different countries, shooting photography with my Fujifilm X-T50 digital camera, watching wildlife documentaries, and playing chess (although I'm not very good at it yet).
