About

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
