Professor Sukhdev Roy received the B.Sc. (Hons.) Physics degree from Delhi Univ. in 1986, M.Sc. Physics from DEI, in 1988, and PhD. from IIT Delhi in 1993. He joined the Dayalbagh Educational Institute in 1993, where he is at present the Head of the Department of Physics and Computer Science. He has been a Visiting Professor at many universities that include, Harvard, Waterloo, Würzburg, Regensburg, Osaka, City University and Queen Mary University of London, TIFR, Mumbai and IISc. Bangalore. He has also been an Associate of the International Centre for Theoretical Physics, Trieste, Italy and is a Member of the Global Panel of MIT Technology Review. Prof. Roy has made significant contributions in Photonics that encompass nano-bio-photonics, silicon and neuro photonics, fiber optics, and optical computing. His experimental and theoretical research on nano-bio-photonic systems that includes low-power and high frequency optogenetic control of neural spiking, defines a new paradigm of technological convergence and innovation and opens up fascinating prospects for energy-efficient, ultrafast and low-cost all-optical information processing, sensing, energy conversion and healthcare. He has won a number of awards and fellowships that include, the, AICTE Career Award for Young Teachers in 2001, JSPS Invitation Fellowship, Japan in 2004, H.C. Shah Research Endowment Prize by Sardar Patel University in 2006, 1st IETE B.B. Sen Memorial Award in 2007, IETE-Conference on Emerging Optoelectronic Technologies Award in 2012, IETE-M. Rathore Memorial Award in 2016, the Systems Society of India’s National Systems Gold Medal in 2016, and the Distinguished Alumni Award by the Dayalbagh Educational Institute in 2021. He also has been awarded seven best paper awards in international and national conferences. He has published 175 research papers in reputed journals and conference proceedings and 11 book chapters. He chaired the 8th World Conference and Expo on Nanoscience and Nanotechnology, Philadelphia, USA in 2020. He has delivered more than 100 invited talks in India and abroad that include Keynote Addresses and Plenary Talks at International Conferences that include the prestigious International Year of Light commemorative Keynote Address, at the 38th Convocation of the International Council of Academies of Engineering and Technological Sciences (CAETS), in 2015 and at the Annual Meeting of American Physical Society in 2008. He was the Guest Editor of the March 2011 Special Issue of IET Circuits, Devices and Systems Journal (UK) on Optical Computing. He is an Associate Editor of IEEE Access and a Fellow of SPIE, the Indian National Academy of Engineering, the National Academy of Sciences, India, IETE (India), and the Optical Society of India.
