Sukumar Basu obtained PhD in solid-state chemistry from Indian Institute of Technology (IIT) Kharagpur, India, in 1973. After completing his post-doctoral research in the Institute of Physical & Theoretical Chemistry, University of Vienna, Austria (1972-1974) with an Austrian Government fellowship and in Max Plank Institute for Radiation Chemistry, Germany (1975-1978) with a research associateship of Max Planck Gesellschaft, he joined Materials Science Centre, IIT, Kharagpur, India as a faculty member in 1979. He taught electronic materials, semiconductors and sensors to both undergraduate & post graduate engineering students. He started research on synthesis, crystal growth and characterizations of electronic materials like silicon and III-V compound semiconductors for solar cell and optoelectronic applications. In 1989 he extended his research to solid state chemical gas sensors. He became full professor in 1995. He visited the State University of Milan, Italy during 1995-96 as the guest scientist with an invitation fellowship of ICTP and the Science City of Japan in Tsukuba during summer of the year 2000 with a senior fellowship of JPS. He attended a number of national and international seminars and conferences in India & abroad and delivered lectures on the subjects of his specializations. After superannuating from IIT Kharagpur in 2005 he joined IC Design and Fabrication Centre, Department of Electronics and Telecommunication Engineering, Jadavpur University, Kolkata, India as Research Advisor. He has supervised more than 20 Ph.D. theses and has published about 200 research articles in the reputed national & international journals. He is a regular reviewer of the international journals ‘Sensors and Actuators B: Chemical’, ‘Sensor Letters’, and ‘Journal of Materials Science-Materials in Electronics’, Journal of Electrochemical Society’, and ‘Journal of Materials Science & Engineering B’. Prof. Basu is the editorial board member of the international journals, Sensor Letters, Sensors & Transducers and Bulletin of Materials Science. He is also the member of the Editorial Advisory Board of the renowned national journal ‘Transactions of Indian Ceramic Society’. He is the joint investigator of a couple of international research projects on the development of solid state gas sensors e.g. a project from Swedish Research Council (2008-2010) and an India-Brazil-South Africa (IBSA) trination project (2011-2014). He is a member of different national and international scientific societies. Prof. Basu is married with two daughters, the elder one is assistant professor of Mathematics, Midwestern State University, Texas, USA and the younger one is senior system engineer, IBM Kolkata, India.
