Radiation Technologies and Applications in Materials Science

Dr. Subhendu Ray Chowdhury currently is a senior scientific officer in Bhabha Atomic Research Centre (BARC), Mumbai, India. He is also a visiting faculty of the Institute of Chemical Technology (ICT) [Formerly UDCT], Matunga, Mumbai, India. Dr. Ray Chowdhury received his PhD in materials science from the Indian Institute of Technology (IIT), Kharagpur, India. After completion of his PhD, Dr. Ray Chowdhury worked for seven years in renown laboratories in USA, including the Department of Materials Science and Engineering, Cornell University; Department of Materials Science and Engineering, Pennsylvania State University. He has published around 70 journal papers, a couple of book chapters, and more that 50 conference papers in radiation-assisted materials development through processing, modification, and synthesis. He has supervised several PhD and post-graduate students. He obtained a couple of patents and transferred many technologies to Industries. His accolades and achievements include National Award for Technology Innovation 2019, by the Ministry of Chemicals and Fertilizers, Govt of India, CSIR research fellowship through NET (National Eligibility Test), and national advisory committee membership of international conferences etc. He was involved in a RCA/UNDP project on “Electron Beam Applications in Materials Science” in 2013, as an international expert committee member from India. He also served as a category A, international faculty on materials science and electron beam for environmental remedy (RCA/UNDP PROJECT) in July 2017, Republic of Korea (South Korea). He is a regular reviewer of more than 25 reputed international journals. As an experienced researcher, he delivers talks as a keynote speaker and invited speaker, and chairs many sessions at international and national conferences.
