I am a 2nd year PhD Student at St John’s College, Cambridge, working at the Cavendish Laboratory Quantum Information Group. I am co-supervised by Dr Sergii Strelchuk (at DAMPT) and Professor Crispin Barnes.

My main interests include quantum algorithms and group-theoretic methods in quantum computing. In particular, I am interested in lightweight benchmarking protocols for restricted computational models (such as Matchgate Circuits), as well as the computational models themselves (such as Permutational Quantum Computing, or Kirkwood-Dirac quasiprobability distributions).

I was born in Krakow, and have lived in the UK since 2011. Prior to my PhD I attended Brasenose College, Oxford, where I obtained a BA in Physics & Philosophy followed by a Master’s in Mathematical & Theoretical Physics.

Aside from my research I supervise the Physics IA course at Emmanuel College, as well as the Mathematics Part II course in Quantum Information and Computation. I also offer private tutoring.
