Bio
Following my undergraduate at Nottingham University, I did my PhD at Durham University in the group of Charles Adams where I demonstrated a strong cooperative optical non-linearity arising from dipole-dipole interactions between Rydberg atoms, using electromagnetically induced transparency to convert the strong atomic interactions onto the optical field to generate large single photon non-linearities, for which I was awarded the Springer Thesis Prize. I then spent two years as a post-doc at Strathclyde, working on the inductive ring trap and building the new BEC apparatus, before moving to the University of Wisconsin in 2013 where I worked on an experiment in collaboration with Mark Saffman and Robert McDermott to develop a hybrid quantum memory for superconducting qubits.
I returned to Strathclyde as an EPSRC Quantum Technology Research Fellow to develop hybrid quantum technologies exploiting atoms coupled to superconducting circuits in order to build devices capable of storing, generating and entangling single photons for quantum networking applications.
I am currently leading an EPSRC Prosperity Partnership with M Squared Lasers called SQuAre: Scalable Qubit Arrays for Quantum Computation and Optimisation to develop a new platform for computing based on arrayd of neutral atoms.
I have funded PhD positions available so please contact me if you are interested.
