I am a PhD student in Programming Principles, Logic and Verification Group at University College London supervised by Alexandra Silva and Samson Abramsky. My current research interests are probabilistic variants of Kleene algebra and their completeness theorems, however more generally I am interested in coalgebraic semantics of probabilistic and quantitative systems.

Before that I received a BSc in Computer Science from the University of Southampton, where I was supervised by Dr Julian Rathke. As an intern, I worked in Software and Large Scale Systems Group in ARM Research in Cambridge, as well as in Goldman Sachs in London.

In my free time, you can usually spot me hiking or horse riding through Polish bits of the Carpathian mountains.
