Staff profile

I graduated from Durham University in 2009 with a BSc in Natural Sciences (Mathematics and Computer Science), and then again in 2010 with a MSc in Internet Technology and Distributed Systems. From October 2010 to June 2016 I studied for a PhD in Complexity Theory under the supervision of Prof. Andrei Krokhin.

For 3 years I was a Teaching Fellow in the Department of Computer Science (formerly the School of Engineering and Computing Sciences). In August 2019 I took on a new role as Assistant Professor (Teaching) in Computer Science with additional responsibility for departmental IT provisions, including management of NCC, our departmental GPU research cluster.
