Research Interests

My research interests focus on the application and development of technology which harness the strengths of diamond colour centres as room temperature single photon sources for use in quantum optics. I am also interested in investigating the spin properties of the negative charged nitrogen vacancy centre which allows manipulation and readout of a single spin at room temperature.
