Born on 1961, Prof. Ray obtained his M.Sc., Physics (1982), M.Tech., Materials Science (1984) and Ph.D. (1991) from IIT Kharagpur. He worked as a Scientist-B for a brief stint in 1984-85 at Solid State Physics Laboratory, Delhi. He joined IIT Kharagpur as a Lecturer in 1991 and rose to the position of Full Professor in 2004 and Professor (HAG) in 2010. He has served as the Head of the Department of Physics (2011-2014), founder Head of the School of Nanoscience and Technology (2014-2016) and Dean, Postgraduate Studies and Research (2015 – 2016) at IIT Kharagpur.

Prof. Ray’s research interest in the broad area of experimental condensed matter physics focusses on semiconductor nanostructures, epitaxial growth of quantum structures, nanophotonics and physics of nanodevices. His research has run the gamut from very practical fields such as pseudomorphic strained SiGe/SiGeC alloy heterostructures for high mobility MOSFETs to low dimensional quantum structures. His studies on Ge quantum dots and strained Ge to achieve light emission from an indirect bandgap semiconductor are useful to realize Si based lasers in future. His research results on floating-gate flash memory, quantum dot infrared photodetectors and nanowire heterojunctions are considered as significant breakthroughs for future nanodevice applications. Prof. Ray has supervised twenty three Ph.D. students (another twelve continuing at IIT Kharagpur) and more than fifty dissertations in UG and PG levels. He has completed 16 sponsored research projects worth over Rs. 18 crore as a PI/Co-PI.

Prof. Ray is a recipient of the INSA Young Scientist Award (1993), Homi J. Bhabha Award (2001), MRSI-ICSC Superconductivity & Materials Science award (2015), MRSI medal lecture award (2007) and CDIL award of IETE (1997). He is a fellow of the Indian Nation Academy of Engineering (INAE) and West Bengal Academy of Science & Technology. Prof Ray has published more than 290 research papers in peer reviewed journals, one US patent, six book chapters and co-authored a book on “Strained Silicon Heterostructures: Materials and Devices” published by IEE, UK. He has served as a visiting faculty / Scientist at the Tokyo Institute of Technology, Japan, University of Delaware, Newark, USA, University of Texas, Austin, USA, Max-Planck Institute for Solid State Research, Germany, Queen’s University of Belfast, UK, National Taiwan University, Taiwan and CGU University, Taiwan. He is an editorial board member of Scientific Reports, Frontiers in Materials : Optics and Photonics – Switzerland, Journal of Nano Energy and Power Research – USA and Nanotrends, India. He serves in a number of national committees that include Research Council member, CGCRI, DST PAC member on Condensed Matter Physics & Materials Science and International bilateral projects, PRSG member, Deity Centers of Excellence in Nanoelectronics and projects approved by the office of the Principal Scientific Adviser to the Government of India
