I am a researcher with a particular interest in the mathematical foundations of quantum information theory. In no particular order, I have worked on: diagrammatic calculi for higher-dimensional quantum systems, measurement-based quantum computation beyond qubits, measures of non-classicality in quantum theory, and quantum computational advantages in continuous variables. Beyond continuing to develop these techniques, I am interested in applying them to more practical problems for near-term quantum computation. A particular focus at the moment is developing algorithms and techniques for the fault-tolerant compilation of quantum computations.
