Yujin H. Kim
Welcome! I'm Yujin, a Ph.D. student in mathematics at the Courant Institute of NYU. I am very fortunate to be advised by Eyal Lubetzky and Ofer Zeitouni.
In Fall 2021, I was a Program Associate at the MSRI for ``Universality and Integrability in Random Matrix Theory and Interacting Particle Systems". Before graduate school, I studied mathematics just up the street at Columbia University.
Broadly speaking, I am interested in probability theory and its applications. Currently, I am thinking about the extremal processes of logcorrelated fields, branching diffusions and their connections with reactiondiffusion equations, random matrix theory, and lattice models in statistical physics. My research is partially supported by an NSF Graduate Research Fellowship and a MacCracken Fellowship.
You can reach me at first name [dot] last name [at] courant.nyu.edu. If you're at Courant, visit me in office 1003!
Here is a rough CV.

"[Fourier] had the opinion that the principal aim of mathematics was public utility and explanation of natural phenomena; but a philosopher like him should have known that the sole end of science is the honor of the human mind."
