Research

Member of the Centre for Quantum Information and Foundations in the Department of Applied Mathematics and Theoretical Physics. Current research interests are quantum foundations, quantum cryptography and quantum information. I am particularly interested in foundational problems involving both spacetime and quantum physics. Within quantum cryptography, I am particularly interested in the investigation of loopholes and practical implementations considering experimental imperfections, mainly within the approach of relativistic cryptography.
