Personal profile
Overview
I am a lecturer with the Accelerator Physics group of the University of Manchester School of Physics and Astronomy and the Cockcroft Institute. I currently work on plasma physics and accelerator topics associated with the study of fundamental properties of antimatter in the ALPHA experiment at CERN. I also conduct research on novel low energy sources for accelerators.
Research interests
Comparing matter and Antimatter through precision measurements with trapped antihydrogen.
The ALPHA experiment at CERN routinely synthesizes and traps antihydrogen atoms. With this unique source of pure antimatter systems, we are able to perform precise measurements of its proerties, from its spectral signature in various energies ranges to its behaviour in a gravitational field. This research is aimed at addressing the question of observed baryon asymmetry in the universe today: why is antimatter so much more rare than matter.
