I am a postdoctoral researcher working in the Superconducting Quantum Detectors group. For the past few years, I have worked on utilizing the nonlinear kinetic inductance of superconducting microstrips for astronomical instrumentation applications. The main focus of the research was creating broadband traveling-wave quantum noise limited parametric amplifiers, which were then used for vacuum noise squeezing experiments and setting new limits on the kinetic mixing parameter of hidden photon dark matter. More recently, I have been keen on expanding this work to explore other potential applications of similar devices, particularly as high efficiency frequency converters and on-chip interferometers.

Lensing of space time around a black hole. At Oxford we study black holes observationally and theoretically on all size and time scales - it is some of our core work.
