I am Group Leader for Sample Environment within the Experimental Operations Division at the ISIS Neutron and Muon Source. More specifically, I am responsible for the development and operational delivery of sample environments for use in neutron scattering experiments, exploring the extremes of temperature, pressure and magnetic field amongst other parameters. The Group also provides support for in-situ gas handling, soft matter, and polarization analysis experiments.
I have a PhD in Low Temperature Physics, and have previously held a Marie Skłodowska-Curie funded position with a world-leading manufacturer of ultra-low temperature equipment.
I am fascinated by the extreme environments found in scientific research. My own research and development interests include ultra-low temperature physics, cryogenics, low temperature thermometry & electronics, and quantum fluids & solids. My previous work has included studies of helium 3 and helium 4 at extremely low temperatures (down to 0.1mK), and commercial development of cooling stages that allow access to the sub-1mK regime.
