Junhyun Park

Researcher, DEEPNOID · M.S., DGIST (2026)

I am an AI researcher at DEEPNOID (alternative military service), working on medical foundation models for chest X-ray, CT, and MRI — vision-language modeling, self-supervised learning, and report generation.

I received my M.S. in Robotics & Mechatronics Engineering and B.E. in Computer Science & Electrical Engineering (double major, summa cum laude) from DGIST, advised by Prof. Minho Hwang. In the summer of 2023, I interned at the Massachusetts General Hospital, Harvard Medical School, advised by Prof. Synho Do and Prof. Kyungsu Kim.

My research aims toward fully automated surgical pipelines — AI-driven diagnosis from medical imaging, coupled with continuum manipulators that navigate natural orifices to perform scar-free interventions.
