Dr. Sinha Ray is also associated with Department of Mechanical and Industrial Engineering as an Adjunct Assistant Professor. He completed his bachelor’s in metallurgical engineering from Jadavpur University, Kolkata and pursued his PhD and Post-Doc from University of Illinois at Chicago under the guidance of Distinguished Prof. Alexander L. Yarin.  Dr. Sinha Ray has published more than 25 articles in peer-reviewed international journals/conference proceedings with an h-index of 14. His research interest is to investigate heat-mass transfer phenomena, energy conversion/storage using nanoarchitecture from polymeric materials. So far, he has been involved with 4 external and one internal research grant (IIT Mandi) of total 182 lakhs. He is currently mentoring 2 PhD students from IIT Mandi, with several MTech students being graduated from his lab. Dr. Sinha-Ray has served as a reviewer for more than 15 international journals, and as guest editor for a special issue in Polymers (MDPI). His group has submitted two Indian patents in 2021 on valorization of waste polymeric materials into value-added products and processes to do the same. Apart from these, he was avidly involved with NSS activities across Mandi town, and he is a sports enthusiast, loves to write and recite poems in his leisure time.
