Rate My Professor Kalyan Gayen

Dr. Kalyan Gayen is an Associate Professor in the Department of Chemical Engineering at the National Institute of Technology Agartala. He possesses a B.Tech., M.Tech., and Ph.D. Following his Ph.D., he undertook a Postdoctoral Fellowship at the University of California, Santa Barbara, USA, commencing in 2007. He has also worked as a postdoctoral research assistant. In addition to his teaching and research roles, Dr. Gayen serves as Associate Dean (Research & Consultancy), Chairman of the Central Research Facility, and Associate Faculty-in-charge for the Scanning Electron Microscope at NIT Agartala.

Dr. Gayen's academic interests encompass bioenergy, systems biology, fermentation technology, and microalgae and cyanobacteria-based biofuels and bioproducts. His research addresses sustainable downstream processing of microalgae, hydrocarbon biorefineries, biobutanol recovery, and triphasic separation techniques for bioproducts such as chlorophylls, proteins, and carbohydrates. He has edited "Hydrocarbon Biorefinery: Sustainable Processing of Biomass for Hydrocarbon Biofuels" and contributed to "Sustainable Downstream Processing of Microalgae for Industrial Application" as well as "Applications of Nanomaterials in Biotechnology, Medicine and Healthcare." With 74 publications listed on IRINS and over 3,234 citations on Google Scholar, key works include "Extraction of chlorophylls and carotenoids from dry and wet biomass of Chlorella vulgaris using ultrasound assisted hot glycerol extraction" (2020), "Simultaneous extraction of chlorophylls, proteins, and carbohydrates from isolated Chlorella thermophila using a triphasic separation technique: A biorefinery approach" (2023), "Effects of carbon, nitrogen, and phosphorus supplements on biomass and biochemical composition of microalgae" (2020), "Design and Economic Analysis of a Thermochemical Biorefinery" (2014), and "Analysis of optimal phenotypic space using elementary modes" (2006). Dr. Gayen has guided three Ph.D. students, advancing biorefinery and bioproduct extraction technologies.
