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. He completed his Ph.D. in Chemical Engineering from Indian Institute of Technology Kharagpur. His research interests include Process Intensification in Chemical Processes, Intensification in environmental process system, Micro-nano bubble science and technology and its applications, Microchannel-based and Jet driven gas-aided extraction, Mineral Beneficiation, Enhanced Oil Recovery by Micro-nanobubble, Multiphase Flow and Reactor Development. He is a Life Fellow of Council of Engineering and Technology (India), Life Fellow of Indian Institute of Chemical Engineers and Fellow of the International Society for Research and Development, London.

He authored four books, five book chapters, has76 conference papers and has more than 100publications in several reputed international journals. He has completed several sponsored and consultancy projects. He has a collaboration with the Aalborg University, Denmark and University of Los Andes, Colombia, Curtin University, Australia, Edith Cowan University, Australia. Presently he is working in the field of Microbubble science and technology and its applications in mineral beneficiation, industrial effluent treatment, and arsenic, ammonia and dye removal and process intensifications in chemical and mineral processing.Dr.  Deepmoni Deka is working as Technical Officer Gr-I in Centre for the Environment at Indian Institute of Technology Guwahati, India. She completed her postgraduation in Molecular Biology and Biotechnology from Tezpur University and Ph.D. in Environment from Indian Institute of Technology Guwahati. Her research interests include bioremediation of environmental pollutants from soil and water, monitoring of ground and surface water quality, nutrient quality, determination of NPK content in soil, purification and characterization of industrial microbial enzymes, bioethanol production using waste biomass, resource recovery, waste valorization, biopolymer based hydrogel. She has 15 research publications in peer reviewed journals, 1 book chapter and more than 25 conference papers. Presently, she is working in the field of biobased plastic production using waste, wastewater treatment specifically pharmaceuticals, dye and heavy metal removal, biopolymer based hydrogel for sensing of pollutants and drugs.
