Atsushi Ueshima is working as an assistant professor at Keio University. He received a PhD in Social Psychology from The University of Tokyo in 2021. In his PhD research, he conducted a series of laboratory and online experiments to understand the psychological bases of inequality aversion and distributive justice. He uses methods from psychology, sociology, and computational social science.
実験室実験やオンライン実験、自然言語データを用いて、不平等や貧困に対して働く心理・意思決定について研究してきました。社会心理学に加えて、社会学や計算社会科学の発想を研究に取り入れています。
