Prof. Dr. Robertus Erdelyi received a Ph.D. degree in applied mathematics in 1996 from the Katholieke Universiteit Leuven, Belgium, followed by the award of Candidate of Science (C.Sci.) in physics in 1997 from the Hungarian Academy of Sciences and Arts, Budapest, Hungary. After completing postdoctoral research at Armagh Observatory, Northern Ireland, U.K., and at the University of St. Andrews, he moved to Sheffield, where, since 2003, he has been a Professor in Applied Mathematics, School of Mathematics and Statistics, University of Sheffield, Sheffield, U.K. He is also the Head of the Solar Physics and Space Plasma Research Centre (SP2RC). His current research interests are in solar physics and solar–terrestrial relations (space weather), using theoretical (analytical and computational) modelling and ground- and space-based observing approaches, in order to understand solar dynamics and plasma heating processes.
