About Me

I am a third year Computer Science PhD student studying at the Department of Computer Science at the University of Warwick. My supervisor is Artur Czumaj. My undergraduate study took place in the same department; I graduated with an MEng in 2019. I am part of the Theory and Foundations group.

From November 2019 to December 2021, I was the Secretary of the Computer Science PGR (Postgraduate Researcher) SSLC.

Research Interests

My current research concerns distributed and parallel computing, particularly fundamental theoretical problems in the CONGEST, CONGESTED-CLIQUE, HYBRID, and MPC models.

The following topics are of academic interest to me:

  • Distributed and parallel algorithms, including communication networks
  • Communication complexity, including multi-party communication complexity
  • Combinatorics, including combinatorial generation


I have been a teaching assistant on the following modules:

  • CS254: Algorithmic Graph Theory (2019/20, 2020/21, 2021/22)
  • CS136: Discrete Mathmatics and its Applications I (2019/20, 2020/21, 2021/22)
  • CS260: Algorithms (2020/21, 2021/22)
  • Warwick Online Learning Certificate (2019/20)
  • CS118: Programming for Computer Scientists (2018/19)
  • CS141: Functional Programming (2018/19)

I was awarded an Undergraduate SSLC Teaching Award for my work on CS254 and CS260 in the 2020/21 academic year. I have been shortlisted for the Warwick Awards for Teaching Excellence in 2021/22.

My office is MB4.17, a shared space in the Mathematical Sciences Building. I am usually seated near the back, on the left-hand side as you enter.

I am mostly working from home but am happy to meet people on campus. If you wish to meet me, either in person or by video call, please send me an email. (This is still the case, as of June 2022.)
