Ryosei Hara

Tokyo, Japan

I am a first-year Master’s student at Keio University, studying in the Isogawa Lab. I major in Computer Vision and Deep Learning. I received my Bachelor’s degree in Engineering from Keio University in 2025.

My research interests cover egocentric vision, event-based vision, and hand-related topics such as hand pose estimation.
