Positions:   Associate Professor, University of Naples Federico II.

Head of the CNR-INFM Activity ”Aspects of macroscopic quantum physics, superconductive and spintronics devices Coherentia Centre (since  2002).

Education: Dr. Pepe’s degree is in Physics (Napoli, Italy, Dottore in Fisica 1988). He had fellowships at CNR and INFM between 1989 and 1993. In 1994 he becomes staff Researcher at the University of Naples Federico II, and in 2003 Associate Professor of General Physics at the same University.

Research Interests/Area of Expertise: Dr. Pepe began his academic career at the University of Naples Federico II, where he tenured in superconductivity, superconducting materials, devices and electronics. He served as Professor of General Physics at the Università del Molise, and Accademia Aeronautica of Pozzuoli until 2006. Within the INFM and CNR-INFM, he served as an associate member from 1994, where he worked on fabrication methods for superconductive circuits, and in particular for superconducting tunnel junction and nanowires for advanced optical detection, and non-destrucctive testing using Superconducting Quantum Interference Devices (SQUIDs) for innovative material (composites) analysis. He developed a long expertise in non-equilibrium superconductivity both theoretically and experimentally, collaborating with many important international scientists from Landau Institute of Moscow, the University of Twente NL, the Univesity of Rochester NY, the South Caroline University USA, and the National Institute of Information and Communications Technology (NICT), Japan. From 1999 he devoted also his scientific interest to the optical characterization of nanoparticles in polymers, toward the investigation of superconductivity on a sub-coherence scale, in collaboration with the CNR-IMCB.

Editorial and Advisory Committees. Dr. Pepe is member of the Organization Scientific Commitee of the 6th European Conference on Applied Superconductivity (14-18 September 2003). Dr. Pepe serves regularly as referee for many journals including the Physical Review Letters, the Phys. Rev. B, the J. of Appl. Physics, the IEEE Trans. Appl. Supercond.,  and the European Phys. Journal D.
