About me
I'm currently an Assistant Professor at Durham University.
I obtained my Ph.D. in 2014 under the supervision of Alex Gamburd at U.C. Santa Cruz, and had postdoctoral positions at I.A.S. Princeton and Yale University.
I'm interested in problems in number theory, dynamics and geometry.
I am from Northern Ireland.

The results of this preprint have now been significantly improved in the paper 'Unitary Group Integrals, Surfaces, and Mapping Class Groups'. On the other hand, this paper contains useful extra background on the more recent results.
