Dibakar Rakshit is a Professor at the Department of Energy Science and Engineering, Indian Institute of Technology Delhi (IIT Delhi). He has twenty years of experience in the thermal design and optimization of energy systems. His expertise lies in computational and experimental multiphase thermal and fluid systems designs which he employs in designing different thermal management systems. These include battery cooling systems for electric vehicles and stationary battery houses, and passive building envelope design for which he has been on the panels of various Government of India (GoI) constituted committees. To name a few - Energy Efficient Technologies of the Bureau of Energy Efficiency, India, Renewable Energy Sources Sectional Committee (MED 04) of the Bureau of Indian Standards, Lighting and Natural Ventilation (CED 46) of the Bureau of Indian Standards.

His Ph.D. at the University of Western Australia in collaboration with Chevron, involved studies of multiphase mass transfer phenomena related to thermal diffusion of sloshing Liquefied Natural Gas (cryogenic fluids). From there, Prof. Rakshit developed his interest in thermal energy storage pursuing it further in his postdoctoral research at the Australian Solar Thermal Research Initiative (ASTRI), Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia. At ASTRI, Prof. Rakshit initiated his studies on ultra-high-temperature thermal batteries (Phase Change Material-based systems). Prof. Rakshit has also worked with multinational companies: Cummins Inc. in the emission control division and GE gas turbine technology.

At IIT Delhi, Prof. Rakshit’s research has been sponsored by the Department of Science and Technology in both national and international programs, the Ministry of Education (MoE), GoI, and many private industries. He has a publication track record of 110 journal publications of international repute, 70 refereed conference papers, and around 25 book chapters and one patent being filed.

Prof. Rakshit has served on the technical committees of numerous international conferences and has coordinated several international conferences. He has served on the guest editorial boards of several international technical journals. Currently, he is also serving as the warden of Zanskar House, IIT Delhi.
