Hi! I am a Ph.D. student in the Graduate School of Information Science and Technology at The University of Tokyo. I am affiliated with the Machine Intelligence Lab and the RIKEN AIP Robot Learning Team, and am supervised by Prof. Tatsuya Harada and Dr. Takayuki Osa.
I am particularly interested in scalable reinforcement learning algorithms for large-scale parallel environments and in dexterous manipulation. Related work was accepted to ICLR 2026.
In summer 2025, I had a great opportunity to work on a dexterous manipulation project Soft Robotics Lab at ETH Zurich. I received my M.S. from The University of Tokyo and my B.Eng. from Kyoto University. Since 2021, I have also been working as a Research Assistant at Sony CSL - Kyoto under Prof. Jun Rekimoto.

Rethinking Policy Diversity in Ensemble Policy Gradient in Large-Scale Reinforcement Learning
ICLR 2026 @ Rio de Janeiro (Poster)
We study multi-policy reinforcement learning in large-scale parallel environments and show how policy diversity affects learning. By appropriately controlling diversity within policy sets, our method achieves high sample efficiency and strong final performance on object manipulation tasks.
