I am a DPhil candidate in the Department of Statistics at the University of Oxford, supervised by Julien Berestycki and James Martin.

I am a member of the St John's College and the Oxford Probability group.

My research interests lie around applied probability and theoretical statistics. My most recent projects were related to Galton-Watson processes and the branching Brownian motion.

I am a student representative at the departamental Graduate Liaison Group and the departamental representative at the Graduate Joint Consultative Forum.


Until April 2020 I was a data science intern at Google.

Non-work activities

  • I enjoy reading non-fiction books over a cup of nice tea, running in the (quite muddy) Oxfordshire countryside and travelling.
  • I speak Polish, English, French and Spanish.
