Paolo Ricci

Paolo Ricci earned his Master's degree in nuclear engineering at the Politecnico di Torino, Turin (Italy) in 2000. His doctoral studies were conducted at the Los Alamos National Laboratory, with focus on kinetic simulation of magnetic reconnection in the Earth's magnetotail. He spent two-and-a-half years as a postdoctoral researcher at Dartmouth College Department of Physics and Astronomy, where he worked on gyrokinetic simulations of the Z pinch. He joined the EPFL Swiss Plasma Center, as a EURATOM fellow in 2006, was named Tenure Track Assistant Professor in June 2010, Associate Professor in August 2016, and Full Professor in October 2023. He is the Director of the Swiss Plasma Center and he heads its theory group. Paolo Ricci is the recipient of the 2016 Section de Physique Teaching Prize, of the 2021 Craie d'Or award from the EPFL physics bachelor students, and of the 2021 Polysphère d'Or award from AGEPoly.
