Harriet Walsh's homepage

I am an assistant professor at the School of Mathematics and Statistics, University College Dublin. I work in discrete probability, and am interested in combinatorial models with interesting algebraic structures and links to statistical physics and random matrix theory. In particular, I like to study random integer partitions.

Prior to joining UCD, I spent two years at LAREMA, Université d'Angers as a postdoc (Centre Henri Lebesgue fellow). Before that, I was a PhD student at the Laboratoire de physique à l'ENS de Lyon, supervised by Jérémie Bouttier and Guillaume Chapuy, and defended my thesis ''New universality classes for random integer partitions'' in October 2022. The manuscript is available here.
