I am a PDRA with the John Adams Institute for Accelerator Science, at Imperial College London. My current research (following on from my PhD at Imperial, 2013) is focused on exploring the physics of high intensity laser plasma interactions, with the particular aim of understanding and optimising the ion beams generated.
The extremely large electric fields produced in laser plasma interactions are orders of magnitude higher than those possible in 'conventional' accelerators, and allow the acceleration of energetic ions (>> MeV/nucleon) over small distances (~micrometers). Such compact ion sources could be useful for medical and industrial applications. Our research group works on investigating the acceleration mechanisms responsible for the energetic particles, and finding ways to create beams more useful for future applications.
