Next Generation Materials and Processing Technologies

Dr. Swarup Bag completed his Bachelors of Engineering in Mechanical Engineering from the Jalpaiguri Government Engineering College, Jalpaiguri, West Bengal, India, in the year 2000, M.E. in Mechanical Engineering in 2002 from Bengal Engineering College, Shibpur, India (now Indian Institute of Engineering Science and Technology), in the year 2002, and Ph.D. on “Development of Bi-directional Heat Transfer and Fluid Flow Model for Reliable Design of GTA and Laser Welding Processes” in 2009 from IIT Bombay. Later he has worked at the Center for Material Forming (CEMEF), MINES Paris Tech, France, for 20 months in Metallurgy, Structure and Rheology (MSR) group. In the year 2011, he joined the Department of Mechanical Engineering, Indian Institute of Technology Guwahati, as a faculty member. He worked as a visiting scholar at Center for Advanced Materials Joining, University of Waterloo, Canada, from May 2018 to July 2018. His primary area of research is fundamental process modelingof welding and joining technologies, optimization of manufacturing processes and recrystallization in metal forming processes. Dr. Bag has published about 50 journal papers, 50 conference papers and 10 book chapters related to welding and joining processes. He is the author of the book “Computational models for GTA and laser welding processes” and the recipient of “Royal Arc Award 2009” from Indian Institute of Welding for the best Ph.D. thesis in welding. Till now, five students have received doctorate degree and seven research scholars are working under his guidance. Thirteen M.Tech. projects and 11 B.Tech. projects have completed so far. Two research projects have completed so far in his credit.  Dr. C P Paul is leading a research group in the area of Laser Additive Manufacturing (LAM) as Head, Laser Additive Manufacturing Laboratory at Raja Ramanna Centre for Advanced Technology (RRCAT). He has over 15 years of experience in research and developmentof LAM, from system development to its applications in engineering and prosthesis. His research programs focus on next generation additive manufacturing system and processes. To this end, his group explores novel techniques to develop advanced materials, innovative products, modeling and simulation tools, and holistic in-situ and ex-situ characterization techniques. He is instrumental in promoting LAM technology in India through collaborations with other national labs and reputed academic institutes by extending the indigenous developed facility for experiments. He has contributed chapters to twelve books and published over 100 research papers.  His extensive experience and leadership have allowed him to address LAM challenges holistically and promoting this strategic research area. His efforts have been recognized with many awards by Indian and Canadian Governments: The indigenous development of first Metal LAM machines in India (for both schemes – Direct Energy Deposition and Powder Bed Fusion) is at his credit and is awarded with DAE Group Achievement Award for the year 2015. As recognition to exemplary works in the development and deployment of laser-baser metal additive manufacturing, he has been conferred with highest DAE Excellence in Science, Technology and Engineering award “Homi Bhabha Science & Technology Award” for the year 2017  NSERC-Discovery Research Grant (Individual) award for repair of Tungsten carbide tools in the year 2007 by Canadian Government during his stay at the University of Waterloo; Ontario Centre of Excellence -Conference Travel Award during the year 2006 by Ontario Provential Government for the laser additive manufacturing process development.  Dr. Mayuri Baruah is currently Assistant Professor at the Department of Production and Industrial Engineering, NIT Jamshedpur, Jharkhand, since 2018. She obtained her B.E. (Civil) from Dibrugarh University, Assam, and Integrated Ph.D. from the Indian Institute of Technology Guwahati, Assam. Her major areas of research interests include welding, additive manufacturing, numerical modeling, characterization and optimization of manufacturing processes. She has published 11 papers in respected international journals and 10 conferences. Till now, 2 research scholars are working under her guidance. 4 M.Tech. projects and 12 B.Tech. projects have completed so far. One minor seed grand research project is running under her.
