Thank you for visiting. I am Shohei Ohsawa, a researcher and entrepreneur. I received my Ph.D. in Engineering from The University of Tokyo in 2015. My research covers machine learning, including multi-agent reinforcement learning, mechanism design, kernel methods, natural language processing, and political economy. I am the sole author of "Truthful Self-Play" (ICLR 2023) and "Support Vector Generation: Kernelizing Large Language Models for Efficient Zero-Shot NLP" (NeurIPS 2025). I founded Daisy Inc. in 2018.
Feel free to contact me!
