The McKay correspondence in higher dimensions »
The McKay correspondence is a surprising, and beautiful, bijection (defined geometrically by du Val, and algebraically by McKay) between the isomorphism classes of Kleinian surfaces singularities and the simply laced Dynkin diagrams.

Using polynomials and complex analysis to check for numerical error in the experimental study of an optimisation algorithm »
Splitting methods are special algorithms that are commonly used to solve optimisation problems for engineering and machine learning.This talk will introduce its main concepts with simple examples, and it features many pictures and the use of dynamical tools for visualisation.

Honeycombs and polytopes: another look at representation theory »
After introducing several geometrical models that can be used to calculate multiplicities in Lie group theory, we describe associated polytopes whose volumes can be considered as approximations of those multiplicities.
