Biography

Adrian Crisan qualified with an MSc (Hons 1st) in Technological Physics from the University of Bucharest, Romania, in 1985 with a thesis on GaAs/AlGaAs hetherostructures laser diodes.

Between 1985-1987 he worked as an Engineering Physicist in the Radiation Detectors R&D group at the Institute for Nuclear Power Reactors Pitesti, Romania.

He joined the National Institute of Materials Physics Bucharest in 1987, studied for a PhD in Condensed Matter Physics (thesis on Superconductivity, viva in 1994) and developed his career in NIMP from Researcher to Senior Scientist Grade 1 (Research Professor).

He has worked in 1997 at University of Southampton (NATO/Royal Society Postdoctoral Research Fellow), in 1998-1999 at University of Rome “Tor Vergata” (Invited Senior Scientist on a grant offered by National Institute of Physics of Matter Italy), in 2000-2002 at the Nanoelectronics Research Institute of AIST Tsukuba Japan (STA Research Fellowships), in 2002-2004 at the University of Bath (PDRA on an EPSRC Grant), and again in 2006 at AIST Tsukuba (JSPS Invitational Fellowship).

In 2006 Adrian was awarded a Marie Curie Excellence Grant of about £1.5 million for his project on self-assembling nanotechnology of pinning centres in superconducting films, for which he choosed the University of Birmingham, School of Metallurgy and Materials as host institution.

In 2007 he became the Leader of the MC Excellence team at UoB
