About Me:

I am currently a postdoc at the University of Cambridge. I completed my PhD at Durham University in 2025, under the supervision of Prof. Michael Magee.

I am interested in topics at the intersection of spectral graph theory, free probability, word maps, random matrices, representation theory and group theory. Here you can read my thesis, entitled `Word maps, random permutations and random graphs'.

Preprints:

Projection formulas and a refinement of Schur-Weyl-Jones duality for symmetric groups. [arXiv]

Submitted.

Random permutations acting on k-tuples have near-optimal spectral gap for k=poly(n). [arXiv] Talk

Submitted.
