My primary research focus is in mathematical and theoretical physics.
I am particularly interested in topological field theory, topological order,
quantum field theory, topological quantum computation, quantum information theory,
quantum computation theory, quantum algebras (especially tensor ceteory, Hopf algbras and related topics),
and the operator algebraic approach to QFT. For more details, please see my Research page.
In addition to my work in mathematics and physics,
I enjoy reading books—two of my favorites are "One Hundred Years of Solitude" and "On the Road"—as well as traveling and writing.
I am also active on several platforms where I engage in popular science communication.
I enjoy discussing interesting topics with people, so feel free to reach out to me via email.
However, please note that currently, I do not have any openings for supervising students for research. Emails of this nature will not receive a response at this time.
Valuable Resources
TQFT: This page will collect some useful information about TQFT, topological order, topological quantum computation, etc.
TQFT ArXiv Daily: This page will be updated automatically every eight hours using arXiv API and Github Actions (modified from This Project). I'm trying to list different topics about TQFT separately, a list of keywords will be given later. I also strongly recommend that you check out Delcamp's ArXiv Digest for TQFT, which is another great resource for staying up-to-date with the latest research in this field.
