I am currently Disglair Lecturer in Astronomy Instrumentation. My cross-disciplinary research draws on developments in condensed matter physics at low temperatures and transfers them to applications that range from astronomical telescopes to quantum computation. My most recent research goes in the opposite direction – turning telescopes around and using them as powerful probes of the behaviour of novel materials at low temperatures.

I am an experimental physicist and enjoy the challenge of building experiments to answer difficult questions. My primary research interest is the physics of novel disordered superconductors, such as granular diamond, and their application to astronomical detectors and quantum devices. Following on from fundamental studies, in my most recent work, I am studying the surprising observation of superconducting phase slip behaviour in three-dimensional superconducting diamond devices and the potential application towards a quantum current standard. I also work closely with industrial partners on the development of continuous cryogenic coolers for both far-infrared astronomical telescopes and as low-cost platforms for quantum computers.
