I am a research associate at the Gravity Exploration Institute at Cardiff University, and I am a member of the LIGO Scientific Collaboration (LSC) and Quantum-enhanced Interferometry for New Physics. In my research career to date, I have experimentally worked and theoretically studied precision optics experiments for fundamental physics.

I concluded my PhD within the PVLAS experiment, which has attained the highest sensitivity for measuring vacuum magnetic birefringence to date. I am still involved (continued from my PhD) in a new initiative VMB@CERN which aims to measure vacuum magnetic birefringence using the static magnetic field of superconducting magnets to overcome the obstacles found in the PVLAS experiment.

In Cardiff, my research has focused on the design and construction of two co-located power-recycled Michelson interferometers for the search of signatures of space-time quantization. The twin tabletop co-located interferometers will also be sensitive to scalar field dark matter and high-frequency gravitational waves. I am particularly interested in a new method for detecting high-frequency gravitational waves based on the graviton-photon conversion in a static magnetic field. I am involved in the design and building of parts of the ultra-low noise enhanced readout electronics for the Advanced LIGO detectors.
