Biography

After obtaining a first-class BA in Mathematics from the Open University (2015),
I completed a PhD in proof complexity at the University of Leeds (2019).
I work currently as a postdoctoral researcher in the Computer Science Institute at the University of Jena.


Research Interests

I continue to work in proof complexity, with particular emphasis on quantified Boolean formulas and models of solving.
My broader interests lie in computational complexity and automated reasoning.
I also maintain a casual and lifelong fascination with theories of natural philosophy.


Publication Record

A complete list of my publications is to be found here.


Scientific Activities

I am serving on the program committee of the QBF workshop 2020.
