I am a project researcher at the ERATO MMSD project in Tokyo. This project aims to extend formal methods and software verification techniques to cyber-physical systems, with particular emphasis on applications to automotive control and manufacturing.

I received a PhD in mathematics at Indiana University in August 2017 as a student of Larry Moss. My academic research interests are primarily in coalgebra, logic, and category theory. Since moving to Tokyo, I have been developing an interest in quantitative refinements of bisimulation and other coalgebraically defined structures. I have also been looking into deep learning and neural networks.
Here are my dblp and Google Scholar pages.
