Prof. Soo-Jin Chua graduated with a B.Eng (Hons) from the University of Singapore in 1974 and his PhD from the University of Wales, United Kingdom in 1977. In 1978, he worked for the Standard Telecommunications Labs, Harlow, UK. In 1981, he spent a year at the Fraunhofer Institute of Semiconductor Technology, Munich under a German Exchange Scholarship (DAAD). He was a Visiting Fellow of Japan Society for the Promotion of Science in 1988 and of the British Council in 1990. Currently, he is Professor in the Depart ment of Electrical Engineering, National University of Singapore, Deputy Director of the Singapore-MIT Alliance (SMA) and Director of the Centre for Optoelectronics. He was Assistant Director of the Institute of Microelectronics from 1991 to 1995. His research area is in optoelectronics and has published over 147 papers in international journals. He has published an undergraduate textbook on Mathematical Physics (MacMillan, 1996) together with Prof Ghatak. Prof Chua is Sr. member of IEEE. He served as Chairman of IEEE, Singapore Chapter from 1984 to 1986 and as Chairman of Education Committee, Region 10 from 1987 to 1988. He has received a number of awards for research and teaching and has consulted extensively for industry in the field of optoelectronics.
