About Me

I am an associate professor in the Department of Computer Science at the University of Warwick.
I am a member of the Division of Theory and Foundations, and the Centre for Discrete Mathematics and its Applications (DIMAP).
I am a founding member and the Computer Science lead of Warwick Quantum.

Prior to joining Warwick, I was a postdoctoral researcher at UC Berkeley.
I received my PhD from the Weizmann Institute of Science, where my advisor was Oded Goldreich.

My research is supported by the following grants:

• UKRI Future Leaders Fellowship, 2020-2027, ~£1.5M
  • UKRI FLF Award, 2020-2024, ~£900K
  • UKRI FLF Renewal, 2024-2027, ~£600K
• EPSRC New Horizons Grant, 2023-2025, ~£200K
• EPSRC Robust and Reliable Quantum Computing Grant, 2023-2025, ~£250K

Research Interests

My research is in Theoretical Computer Science and Quantum Computing.
I am particularly interested in Classical and Quantum Complexity Theory, Algorithms, Coding Theory, Learning Theory, and Cryptography.

My Group

I am fortunate to advise the following PhD students and postdocs:


Prospective students and postdocs: I am interested to hear from potential PhD students and postdocs with a strong TCS/maths background.
If our research interests intersect and you would like to work with me, feel free to drop me a line.
