Brad Ryan

Profile

I am a third-year PhD student within the Algebra, Geometry and Integrable Systems Group. Before starting as a postgraduate researcher, I completed my undergraduate course at the University of Leeds. During this time, I did a short investigation into hyperbolic geometry under Dr Derek Harland in 2019, as well as a longer project studying knot theory with Professor Martin Speight in 2020.

Research interests

My current research is focused on understanding the connection between the double affine Hecke algebra of type \(BC\) and the character variety of a four-punctured Riemann sphere with prescribed eigenvalues (the Calogero-Moser space). Directly related to this is the representation theory of a star-like quiver, namely the affine quiver \(\widetilde{D}_4\) with an additional vertex on one of its legs.
