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. He has received several awards like; Dr. A.V. Rama Rao Foundation’s Best PhD Thesis and Research Award in Chemical Engineering from IIChE (2007), BOYSCAST Fellow award (2009-10) from the DST, Young Engineers Award in the field of Chemical Engineering from the Institute of Engineers (India, 2009), Young Scientist Medal award from the Indian National Science Academy (INSA, 2009). His current research activities are focused in four distinct areas viz. i) membrane synthesis and separation technology (both ceramic and polymeric), ii) water pollution control, iii) smart material and iv) adsorption. In each of the area, his goal is to synthesis responsive materials and to develop a more fundamental understanding of the factors governing the performance of these technologies. He has more than 15 years of experience in academics and research and published more than 125 papers in different reputed journals of importance. He has submitted 7 patents and involved with more than 12 sponsored projects from various funding agencies. Dr. Purkait has guided 12 numbers of PhD students and 5 are yet to get their PhD degree. He has edited one book (Taylor & Francis, Cat. #: K10293, ISBN: 9781439805268) and written one text book in Springer (In Press). Mr. Randeep Singh in the year 2011 received his undergraduate (B.Tech.) degree from Kurukshetra University in Biotechnology and Masters (M.Tech.) degree in Chemical Engineering from National Institute of Technology Trichy, Tamilnadu. Presently he is pursuing doctoral research in the Department of Chemical Engineering at Indian Institute of Technology Guwahati, Assam. His research work is dedicated to prepare various membranes and mathematical analysis of the transport phenomena in membrane separation processes including wastewater treatment, fruit juice clarification, protein separation, value added product separation from biogenic source etc. He is also working on fabrication of different membrane modules for environmental separation. He has already submitted 6 papers in international journals and presented five papers in national and international conferences. He has received several Awards in his field including young scientist award in International Science Congress (ISC-2015) held in Nepal. He is an associate member of Indian Institute of Chemical Engineers.
