Alexander is a theoretical and computation plasma physicist specialised in laser-plasma physics based in the CLF. He leads the Plasma Physics Group (PPG). As an expert in laser-plasma physics, his role in the CLF is twofold. Firstly, it is to engage in collaborative research with CLF users through his application of complex theory and numerical simulations. The users are predominately experimentalists, and his involvement enhances the outcomes of the experiments and their impact. Secondly, it is to conduct independent research in areas that he personally finds interesting and stimulating.
He graduated from the University of Cambridge in 2002 with a BA in Natural Sciences and an MSc in Experimental and Theoretical Physics. He went to to do a PhD at Imperial College London, which he was awarded in 2005. The same year, he began work at the CLF as a Theoretical Plasma Physicist. Ten years later, in 2015, he became the Plasma Physics Group Leader.
Research interests: fast electron transport, fast electron generation, ion acceleration, inertial fusion via advanced ignition, low frequency radiation from laser sources, fundamental plasma physics, hydrodynamics
