Masashi Hatano

Postdoc at The University of Tokyo

prof_pic.jpg

I am a Postdoc at The University of Tokyo working with Prof. Yoichi Sato.

Previously, I was a PhD student at Keio University supervised by Prof. Hideo Saito. During May 2024 and May 2025, I conducted research at the University of Bristol as a visiting PhD student and working with Prof. Dima Damen.

My research interests span the broad area of machine learning, computer vision, egocentric vision, human motion understanding, and future forecasting.

In 2023, I obtained a Master’s degree in computer science from Keio University, Japan, and an engineering degree from CentraleSupélec, France, as part of a double degree program.
