Optical Sensors for Biomedical Diagnostics and Environmental Monitoring

B.D. Gupta received his M.Sc. degree in physics (1975) from Aligarh Muslim University (India) and a Ph.D. degree in physics (1979) from the Indian Institute of Technology, New Delhi. In 1978 he joined the Indian Institute of Technology, New Delhi, where he is currently a professor of physics. In addition, Prof. Gupta has worked at the University of Guelph (Canada) in 1982-1983, the University of Toronto (Canada) in 1985, the Florida State University (USA) in 1988, the University of Strathclyde (UK) in 1993 and the University of Birmingham (UK) in 2010. In 1992, he was awarded the ICTP Associateship by the International Centre for Theoretical Physics, Trieste (Italy), which he held for 8 consecutive years. In this capacity, he visited ICTP (Italy) in 1994 and 1996. Prof. Gupta is a recipient of the 1991 Gowri Memorial Award of the Institution of Electronics and Telecommunication Engineers (India). He has published more than 90 research papers in international journals and 65 papers in conferences. Prof. Gupta is authored a book entitled Fiber Optic Sensors: Principles and Applications (NIPA New Delhi, 2006) and is the Co-Editor of the Proceedings of SPIE (USA) Vol. 3666 (1998) and Vol. 8173 and Advances in Contemporary Physics and Energy (Supplement Volume) (Allied Publishers, New Delhi). Prof. Gupta is in the Editorial Board of the journals ISRN Optics and Chemical Sensors. His current areas of interest are plasmonics, fiber optic sensors and nanotechnology. He is a regular member of the Optical Society of America and life member of the Optical Society of India and the Indian Chapter of ICTP.
