Dr Sourav Mondal Dr Sourav Mondal has done his PhD in Chemical Engineering from the Indian Institute of Technology Kharagpur. Presently he is working as a post-doctoral researcher in the University of Oxford. His research work is dedicated to various modeling and mathematical analysis of the transport phenomena in different separation processes including membrane based filtration of wastewater treatment, fruit juice clarification, dye separation, bio-product separation, mixed matrix membrane filtration, etc. He is also working on modeling of adsorption, microfluidic mass transport, computational fluid dynamics of multiphase separation processes and other fluid dynamical processes as well as environmental challenges. He has been the recipient of Shastri Indo-Canadian research mobility award in 2012-13 as a part of the scientific and innovative exchange program between the two nations. He has already authored two books, one book chapter, one patent, more than thirty publications in international journals of repute and presented at several international conferences. Prof. Mihir Kumar Purkait 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, 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 of responsive materials and to develop a more fundamental understanding of the factors governing the performance of these technologies. He has more than 12 years of experience in academics and research and published 135 papers in different reputed journals of importance. He has submitted 7 patents and involved with 14 sponsored projects from various funding agencies. Dr. Purkait has guided 13 PhD students and 7 are yet to get their PhD degree.
