About me:

I am an assistant professor at National Institute of Informatics (NII). Before joining NII in 2020, I spent two years as a JSPS postdoctoral fellow, hosted by Prof. Satoru Iwata, at University of Tokyo, and by Prof. Makoto Yokoo, at Kyushu University. I completed PhD at the Department of Computer Science, University of Oxford, under the supervision of Prof. Edith Elkind. My research focuses on algorithmic game theory and computational social choice, in particular fair division of divisible and indivisible items. My research is supported by JST PRESTO (Dec. 2020 - Mar. 2024). I am currently looking for Ph.D students to work on my research projects (as research assistants). Please contact me if you are interested.


July 2022: I will co-present a tutorial at IJCAI 2022 with Warut Suksompong on Constraints in Fair Division.
