Department of Computer Science and Technology

  • Research Fellow

I am a Postdoctoral Research Fellow in the Department of Computer Science and Technology at the University of Cambridge. I work closely with Prof. Tom Gur and Dr. Sergii Strelchuk in the Algorithms and Complexity theme.

I recently obtained my PhD in Applied Mathematics (Quantum Information) from the University of Waterloo, Canada. I was supervised by Prof. Joseph Emerson and was a part of the Institute for Quantum Computing. My thesis can be found here.


  • Quantum computing
  • Classical and quantum error correction
  • Quantum error characterization
  • Theoretical computer science

In particular, my research focuses on assessing and reducing the resource requirements for quantum fault-tolerance schemes. I am also interested in the complexity of key tasks in classical and quantum error correction.


I am currently supervising Computer Science Part II Quantum Computing course.

I lectured the Applied Linear Algebra I course at the University of Waterloo during Spring 2022. The course had over a hundred undergraduate students and was taught completely online.
Topics : Systems of linear equations, Matrix algebra, Determinants, Introduction to vector spaces, Applications.

I am fortunate to co-supervise Debankan Sannamoth, who is a Master's student at the University of Waterloo working with Prof. Joseph Emerson.
