I'm a researcher at Microsoft Research and a member of the QuArC group.

I'm also a reader in the Computer Science Department of University College London.

My research is on quantum information science. I explore the interplay of computer science, mathematics, and physics to study the role of quantum mechanics in computation and information transmission.

**Research Interests:**

- Quantum information theory and entanglement theory

- Quantum hamiltonian complexity and quantum many-body physics

- Quantum complexity theory and quantum algorithms

- Connections of quantum computation and information to computational complexity,

optimization, resource theories, and thermodynamics
