Keigo Kusumegi

CV (July 2025)

I'm Keigo, a Ph.D. student in Information Science at Cornell University advised by Yian Yin.

My research focuses on understanding collective behavior and the interactions between individuals and society that drive innovation and success. To explore these topics, I apply methods from Network Science, the Science of Science, and Computational Social Science.

Currently, I am working on projects that examine team science in interdisciplinary collaborations and the impact of Large Language Models on scientific progress and innovation.

I previously studied at the University of Tsukuba, Japan.
