About

I am a PhD student working on theoretical physics, focusing on quantum field theory, gravity, and related topics. My supervisor is Toshifumi Noumi at Komaba High Energy Theory Group. I am currently exploring deep learning techniques to apply them to my research in particle physics and cosmology.

初めまして! 私は駒場素粒子論研究室に所属する 野海俊文氏に指導を仰ぎながら、 場の量子論や重力理論を中心に理論物理学を研究している博士課程の大学院生です。最近、深層学習の勉強を始めており素粒子理論や宇宙論研究への実装をしたいと思っています。
