Research Scientist
NTT Human Informatics Laboratories, NTT Corporation
My research focuses on leveraging computational power to understand and improve human behaviors, decision-making processes, and communication patterns by modeling the psychological aspects of humans within computing systems.
My areas of interest include human-AI interactions and computational social science.
Apr. 2025: I attended CHI 2025 in Yokohama, Japan. Thank you all for sharing and discussing our idea. So inspiring! See you next time!
Jan. 2025: 🎉 Our paper "The Role of Initial Acceptance Attitudes Toward AI Decisions in Algorithmic Recourse" has been conditionally accepted at CHI 2025! The acceptance rate is 24.9%! (later officially accepted in Feb. 2025)
May 2024: 🎉 Our paper "Reassessing Evaluation Functions in Algorithmic Recourse: An Empirical Study from a Human-Centered Perspective" has been accepted at IJCAI 2024 Special Track on Human-Centered AI! Surprisingly, the acceptance rate is 5.5% (11/199)!
Jun. 2023: 🏆 Our paper "Personal History Affects Reference Points: A Case Study of Codeforces" won the best paper award, Outstanding User Modeling Paper, at ICWSM 2023! Congrats to our first author, Dr. Takeshi Kurashima!
