Jiwoon Park / 박지운

I am currently serving my mandatory military duty as a mathematics instructor at the Republic of Korea Air Force Academy.

Background

I attained a Ph.D. degree in mathematics at the University of Cambridge. My advisor was Roland Bauerschmidt.

• Here is a link to my thesis: Two-Dimensional Discrete Gaussian Model at High Temperature

Research Interests

My main research field is the lattice field theory, which is in the intersection of probability theory and mathematical physics.

I work with renormalisation group method.
