I am a Marie Skłodowska-Curie Research Fellow working with the John Adams Institute for Accelerator Science, at Imperial College London.  My research (following on from my PhD and postdoc at Imperial, 2013, JSPS Fellowship  (2015-2017) and QST Postdoctoral Fellowship (2017-2020) at Kansai Photon Science Institute, Japan) is focused on exploring the physics of high intensity laser plasma interactions, with the particular aim of understanding and optimising the ion beams generated. 

Although still in their infancy, high-power-laser driven ion accelerators are an alternative to conventional accelerators, providing beams with novel properties and resulting in new applications.  A high-power-laser is focused onto a target, ionising atoms and heating freed electrons, which stream away from the laser focus. As the target ions remain relatively static due to a significantly lower charge-to-mass ratio, a charge imbalance is created, generating an extreme electrostatic field, accelerating ions to >MeV energies in ~μm distances.


Although low laser repetition rate limits the average current, the extremely high peak current at source is of kiloampere order. This motivates a number of applications distinct from conventional ion sources, such as radiography of high energy density physics experiments, generation of warm dense matter, ultrafast material response studies, material processing, high dose radiobiology and as high energy, high peak current injectors into a conventional accelerator.

My current research is supported by EU’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No. 894679
