Professor Suhash Chandra Dutta Roy earned his B.Sc.(Hons.) degree in Physics in 1956, the M.Sc.(Tech.) degree in Radio Physics and Electronics in 1959, and the D.Phil. degree for research on Network Theory and Solid State Circuits in 1965, all from the University of Calcutta , India.
He served the River Research Institute, West Bengal, as a Research Officer for two years, the University of Kalyani as a Letcturer for four years, and the University of Minnesota, USA, as an Assistant Professor for three years, before joining the Indian Institute of Technology Delhi (IITD) as an Associate Professor in 1968. He was promoted to a full Professorship in 1970, and served the IITD for more than four decades in various capacities – as Head of the Department and Dean of Undergraduate Studies while in active service, and after superannuation in 1998, as IITD Emeritus Fellow, Indian National Science Academy (INSA) Senior Scientist and INSA Honorary Scientist. Currently he holds the title of INSA Emeritus Scientist.
He has held Visiting Professorships at the University of Leeds, UK and the Iowa State University, USA for one year each, on sabbatical leave.
He still maintains an active research interest in circuits, systems and signal processing, and still publishes research papers on these topics. He has published two books, entitled Circuits, Systems and Signal Processing (Springer, 2008) and Topics in Signal Processing (Springer, 2009) and more than 250 research papers in IEEE, IEE and other high SCI impact paper journals.
Professor Dutta Roy is the recepient of many awards and recognitions, including Honorary D.Sc. degrees from the Indian Institute of Science Education and Research, Shibpur, and the Dayalbagh Educational Institute (Deemed University), Agra; national prizes, including those named after Shanti Swarup Bhatnagar, Vikram Sarabhai, and Pandit Jawaharlal Nehru; Fellowships of the IEEE and of all the national academies in science and engineering; and Distinguished Fellowship of the IETE. He has recently been named as the winner of the IEEE Signal Processing Society Distinguished Teacher for the year 2022.
What Professor Dutta Roy values most is the love and appreciation of his large number of direct as well as virtual (through NPTEL lectures on the internet) students and professional colleagues spread throughout the world.
Besides the subjects of his research interests, he maintains a deep interest in Indian Classical Music.
