Experimental high-energy particle physics; Radio-frequency superconductivity in metallic films.
I am interested in collisions between the most elementary particles available, at the highest possible momentum transfer, and have been involved in the development of instrumentation to do observe them. One focus is the limiting behaviour of niobium and films of niobium and niobium alloys used in superconducting radio-frequency cavities, the aim being to increase the affordable energy of a future linear collider. Previously, I studied high momentum transfer elastic scattering and electron-positron annihilation (ARGUS at DESY). I also participated in the development and construction of the ZEUS calorimeter at DESY, which led to observations that challenged the Standard Model of particle physics.
