I'm a researcher interested in conducting precision measurements of fundamental quantities using cold molecules. I work in the Centre for Cold Matter, part of the department of physics at Imperial College, London.
My main focus is to measure the size of the electron's electric dipole moment using ytterbium fluoride molecules. This is an important quantity to measure because if the electron's dipole moment is non-zero, this violates time-reversal symmetry and it would be evidence for new physics beyond the Standard Model. You can read much more about the technical details of how the experiment works on our website, or listen to me trying to explain the essence of what we're trying to do here.
I'm also interested in 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.
