Muon g-2. I began a research effort at Oxford to develop a calibration magnetometer for the muon g-2 project, at Fermilab in the USA. This experiment will search for new physics by measuring the anomalous magnetic dipole moment (or ‘gee minus two’ factor) of the muon.

The Neutron. The shape of the neutron, or more formally, its electric dipole moment, is linked to the fundamental symmetry which separates matter from antimatter. Measuring this could help reveal how the Universe we know came to be. I worked on this challenge, building a SQUID magnetometer for the cryoEDM experiment, to track changes in the magnetic field inside the neutron cells to sub-picotesla precision.

Geophysics. Novel magnetic sensors could reveal new geomagnetic phenomena. I installed SQUID sensors in underground tunnels at the Rustrel laboratory in SE France, to search for magnetic jumps linked to groundwater flow. This technology could also let us probe underground using the technique of magnetotellurics.

Dark Matter. Dark matter has been one of biggest unsolved mysteries in science since I was a student. I worked on cryogenic detector readout for the CRESST dark matter search at the Gran Sasso underground laboratory in central Italy, and was also involved with the EDELWEISS and EURECA projects.

My duties include tutoring mathematics for first year physics students in Hertford College. I am a senior demonstrator in the nuclear physics teaching lab. For three years, I gave the first year lecture course on circuit theory, and I have given problem classes for the C4 Particle Physics Major Option.

At public events like Stargazing Oxford, the Oxfordshire Science Festival, and ATOM Festival, I am usually found running the particle physics outreach stall, enthusing about fundamental science to young people using Lego bricks and Particle Zoo toys. I am now planning a popular science book about my adventures at underground laboratories around the world.
