Professor Sukhdev Roy received the theBSc (Hons) Physics degree from Delhi Univ, in 1986, MSc Physics from DEL in 1988, and PhD from ift Delhi in1993. He joined the DayalbaghEducational Institute in 1993, where he is at present the Head of theDepartment of Physics and ComputerScience. He has been a Visiting Professor at many universities that include, including Harvard (USA) Waterloo(Canada), Würzburgand Regensburg (Germany) Osakajapan) City University, and Queen Mary University of London (UK) TIFF, Mumbai, and Sc Bangalore (india). 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-blo-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, 15PS Invitation Fellowship, japan in 2004, HC Shah Research Endowment Prize by Sardar Patel University in 2006, 1st IETE BB 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.
