My research is broadly focused on string theory and quantum field theory. Recently I have been interested in symmetries and their generalization to "categorical" or "non-invertible" symmetries, as well as in revisiting subtle, topological issues in string theory. My previous work has explored string perturbation theory, its connections to number theory, and various topics in (super)conformal field theory.
Message
Symmetry plays a central role in modern theoretical physics, featuring in contexts ranging from the characteristics of crystals to the classification of elementary particles. Despite its prolific use in physics over the last century, the past decade in particular has seen surprising changes in our understanding of the notion of symmetry. Especially noteworthy are so-called "categorical" or "non-invertible" symmetries---distinctly quantum mechanical symmetries based on the phenomenon of "quantum superposition." Just as conventional symmetry has played a central role in modern physics, categorical symmetry is expected to contribute significantly to physics going forward.The current research aims to bring about new insights across various subfields in high-energy physics, and to contribute to the advancement of physics at large. I hope that this study will stimulate researchers across multiple disciplines, in alignment with the overarching goals of the Inamori Frontier Program, as it endeavors to engage in impactful research. Alongside the other faculty in this program, I hope to push the frontiers of human knowledge and inspire the next generation of scientific inquiry.
