Prof. Joseph Micallef received his B.Sc.Eng. (Hons) degree in electronics engineering from the University of Malta, in 1972 and the M.Sc. and Ph.D. degrees in electrical engineering from the University of Surrey, U.K., in 1989 and 1993, respectively. From 1973 to 1981, he was with General Instruments, engaged in work on high-voltage components and circuits and on IFT's. He moved to SGS-THOMSON Microelectronics in 1981 where he was involved with packaging of MOS IC's. In 1989, he joined the Faculty of Engineering at the University of Malta and is currently head of the Department of Microelectronics. His current research activities include analogue integrated circuit design as well as optical properties of III-V quantum well structures.
