Xunjie XU (许勋杰) is a theoretical particle physicist currently working at the Institute of High Energy Physics (IHEP), Beijing, China. Before joining IHEP, he was a postdoctoral researcher at the Université libre de Bruxelles (ULB), Brussels from 2020 to 2021, and the Max-Planck-Institut für Kernphysik (MPIK), Heidelberg from 2016 to 2020. His research covers neutrino physics, BSM physics, and most recently, cosmology. For further details, see the inspirehep link.
