Aarón Alejo is an experimental Plasma Physics researcher, working on laser-plasma interaction, and particularly laser-driven particle accelerators. He obtained his PhD in Plasma Physics at Queen’s University Belfast for work on novel ion acceleration mechanisms and their potential as drivers of bright neutron sources. Following his PhD, he became a Research Fellow at Queen’s University Belfast, working on the laser wakefield electron acceleration and generation of positron beams and electron-positron plasmas. He then took a postdoctoral research position at the University of Oxford, where he worked on electron acceleration and generation of plasma waveguides for high-intensity lasers.

After being awarded a MSCA-laCaixa Junior Leaders fellowship, in 2021 he joined the Galician Institute for High Energy Physics as a junior researcher, while he also lectures at the Universidade de Santiago de Compostela. In 2023, he was awarded a prestigious Ramón y Cajal tenure track fellowship. Currently, his research focuses on laser-driven ion acceleration and applications using commercial laser systems, with a stress on medical applications such as the production of radioisotopes relevant for PET imaging.
