Department of Computer Science and Technology

  • Senior Research Fellow

I am an 1851 Research Fellow at the Department of Computer Science and a College Research Associate affiliated to Sidney Sussex College. I formerly held positions as an Assistant Professor (Research-focused), Research Fellow, and Postdoctoral Research Associate in the Department of Computer Science at the University of Warwick between September 2020 and August 2023.

Research Interests

  • Theoretical Computer Science
  • Quantum Computing
  • Quantum Information

Most of my recent work addresses (quantum) Algorithms and Complexity Theory, Learning Theory, Machine Learning, and Property Testing. I am also more broadly interested in Theoretical Physics.
