He was a Lecturer with the University of Liverpool from 1979 to 1983 and with the University of Bath, where he became a Senior Lecturer in 1986, a Reader in 1990, and a Professor in 1995. He was a Visiting Researcher with the Center for High Technology Materials, University of New Mexico, Albuquerque, USA, in 1987. In 1989, he was a Visiting Researcher with the Huygens Laboratory, Leiden University, The Netherlands. From 1990 to 1991, he was with the Teledanmark Research Laboratory and the MIDIT Center of the Technical University of Denmark, Lyngby. He was a Guest Researcher with the Electrotechnical Laboratory, Tsukuba, Japan, in 1991. In 1992, he was a Visiting Professor with the Department of Physics, University de les IllesBalears, Palma–Majorca, Spain. He was a Visiting Lecturer with the Instituto de Fisica de Cantabria, Santander, Spain, from 1996 to 1998, and a Visiting Researcher with the Department of Physics, Macquarie University, Sydney, Australia, in 1996, 1998, 2000, 2002, 2005, and 2008.
