Andrew Ahn
I am currently an NSF Postdoctoral Associate (Visiting Assistant Professor) at Cornell University. In 2020-2021, I was a Joseph F. Ritt Assistant Professor at Columbia University. I received my PhD in Mathematics at MIT under Vadim Gorin.
I work in integrable probability with a focus on random matrices, asymptotic representation theory, and dimer models.
Here is my CV.
