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

I'm interested in the interplay of computer science, mathematics, and physics for

studying the role of quantum mechanics in information processing and computation.

My research is part of a bigger effort on quantum information science at UCL.

**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
