Tomohiko Yokoyama
My interests have focused particularly on the intersection of machine learning and platforms, as well as how to leverage LLMs in agentic applications. With practical experience in algorithm and AI implementation, I am passionate about bridging the gap between research and real-world applications. Currently working as an Applied Research Engineer at Sakana AI. I received my PhD in Information Science and Technology from the University of Tokyo under the supervision of Prof. Satoru Iwata, specializing in optimization, mechanism design, algorithmic game theory, and machine learning.
