Gilyoung Cheong

  I am a PhD candidate in the Department of Mathematics at the University of Michigan. My advisor is Michael Zieve. Here is my CV.

  My research involves statistics of various algebraic objects. For example, I am interested in distributions of numbers of points on random curves over a finite field, cokernels of random p-adic matrices, and lengths of cycles in random permutations. In the language of schemes in algebraic geometry, all such distributions, as well as many other ones in literature, admit some "independence phenomena" over closed points of a base scheme, which provides a major theme of my current research. Various tools from other fields such as analytic number theory, combinatorics, and probability theory can also come into play, on top of algebraic methods. I do not classify myself in a single field, and I can work with any mathematician with some common ground!
