I am an associate professor at Durham University.
I graduated in 2011 from the University of Edinburgh under the supervision of
Professor Andrew Ranicki, and I was a Zorn Postdoctoral Fellow at
Indiana University in Bloomington from 2011 - 2014.
For the academic year 2014 - 2015
I visited the Max Planck Institute for Mathematics in Bonn.
From 2014 to 2017 I was an assistant professor in the CIRGET lab at the Université du Québec à Montréal (UQAM).

I work on topology, specifically the theory of manifolds. I specialise in the topology of 4-dimensional manifolds and the concordance of knots and links.

I am an editor of the Proceedings of the Edinburgh Mathematical Society.

I am a guest editor of a special issue of the Proceedings of the Royal Society of Edinburgh Section A, in honour of Andrew Ranicki.
