I'm a researcher interested in conducting precision measurements of fundamental quantities and new physics searches using table-top experiments. I used to work in the Centre for Cold Matter, part of the department of physics at Imperial College, London, and I'm now a visiting researcher at Imperial College and a CERN staff member, working in the BASE collaboration. From September 2022 I'll be returning to Imperial as a Royal Society University Research Fellow.

My research interests include

  • Measuring the size of the electron's electric dipole moment using ytterbium fluoride molecules
  • Simulating the behaviour of complex multi-level molecular systems when they interact with many electromagnetic fields. This helps us understanding how to apply techniques like optical pumping, laser cooling and magneto-optical trapping trapping to molecular systems.
  • Testing CPT symmetry by comparing the properties of protons and antiprotons
  • Searching for dark matter using superconducting LC circuits
  • Using Penning traps to detect dark matter
