Hi, I’m Takeshi Teshima, a data scientist at Recruit Co., Ltd. I am also a part-time lecturer at the School of Management, Tokyo University of Science, where I teach courses on machine learning and introduction to artificial intelligence.

I formerly served as a Junior Research Associate at RIKEN AIP, a distinguished national research center, while also being a grantee of the Masason Foundation.

I earned a Ph.D. in science with a focus on machine learning, under the mentorship of Masashi Sugiyama at the Sugiyama-Yokoya-Ishida Lab, from the Graduate School of Frontier Sciences, UTokyo in 2022. Prior to that, I obtained my B.Econ from the Department of Economics in 2017.

I’ve been fortunate to work closely with Professor Issei Sato, Professor Isao Ishikawa, and a host of other exceptional collaborators in the past. Moving forward, I am eager to channel my innovative ideas towards “AI for Good” initiatives.
