About Me


I am a Post-Doc fellow at RIKEN Center for Quantum Computing, Mathematical Quantum Information RIKEN Hakubi Research Team of Dr. Bartosz Regula.
I was a Post-Doc fellow at Nagoya University and JSPS Reserach Fellow (No. JP22J14947). I recieved Ph. D. at Graduate school of mathematics, Nagoya university, Japan, under the supervision of Prof. Francois Le Gall. I received a Master of Mathematical Science degree from Graduate School Mathematics at Nagoya University in 2020 under the supervision of Prof. Masahito Hayashi and B. E. degree from Department of Sciences at Kyoto University in 2018.

My curriculum vitae is available here (on updating). You can also find me on arXiv, ORCID, and ResearchGate.


Research Interests
