Colin McSwiggen

, a PhD candidate in the Division of Applied Mathematics at Brown University. I try to answer questions in enumerative geometry and combinatorial representation theory with a toolkit drawn from random matrix theory, integrable systems, geometric quantization and stochastic analysis.

My advisor is Govind Menon. In 2018-19 I also worked with Jean-Bernard Zuber as a Chateaubriand Fellow at the Laboratoire de Physique Théorique et Hautes Energies, Sorbonne University.
