Dr. Mihir Kumar Purkait is a Professor in the Department of Chemical Engineering at Indian Institute of Technology Guwahati (IITG). Prior to joining as faculty in IITG (2004), he has received his PhD and M. Tech in Chemical Engineering from Indian Institute of Technology, Kharagpur (IITKGP) after completing his B. Tech and B. Sc (Hons) in Chemistry from University of Calcutta. His current research activities are focused in four distinct areas viz. i) advanced separation technologies, ii) waste to energy, iii) smart materials for various applications and iv) process intensification. In each of the area, his goal is to synthesis stimuli responsive materials and to develop a more fundamental understanding of the factors governing the performance of the c^12,500, h-index = 64, 10 index = 150). He has authored 10 books in CRC press and Elsevier in last 5 years.Dr. Subrata Kumar Majumder is a Professor in Chemical Engineering Department at Indian Institute of Technology Guwahati, India.
