Dr. Debabrata Das pursued his doctoral studies from Indian Institute of Technology (IIT) Delhi and post-doctoral research work at University of Utah (UU), USA. He was associated as a MNRE Renewable Energy Chair Professor for three years and Professor for 32 years at IIT Kharagpur. He was also associated as INAE-AICTE Distinguished Visiting Professor of SRM Institute of Science and Technology, Chennai and Heritage Institute of Technology, Kolkata. Presently, he is the Scientific Advisor of M/s. Dhampur BioOrganics Ltd., New Delhi.

He is actively involved in the research of hydrogen biotechnology for a period of more than twenty five years. His commendable contributions towards development of a commercially competitive and environmentally benign bioprocess for the biohydrogen production from organic wastes using both mesophilic and thermophilic microorganisms. His recent work on biohythane process for the maximization of gaseous energy recovery from the organic wastes is worth mentioning. 10 m³ biohydrogen pilot plant was demonstrated and successfully carried out. Technology License agreement of the process has already been transferred to M/s. Dhampur Sugar Mills Ltd. He is the author of the five text books: "Biohydrogen Production: Fundamentals and Technology Advances"; "Fundamentals of Biofuel Production Processes" and "Industrial Biotechnology" published by M/s. CRC Press, New York and "Biohythane: Fuel for the future", "Biochemical Engineering: An Introductory Text Book" and "Biochemical Engineering: A Laboratory Manual" published by M/s. Pan/Jenny Stanford Publishing, Singapore. He is the Editor of the books entitled "Algal Biorefinery: An Integrated Approach" and "A bioelectrochemical system that convert wastes to Watts" published separately by M/s. Springer, Switzerland and M/s. Capital Publishing Company, India. He has three Indian patents. He has the Google h-index of 65 for his research work. He has more than 180 research publications in the peer reviewed journals and contributed more than 41 chapters in the books published by International publishers. He offered two NPTEL 12-weeks courses on Industrial Biotechnology (has been offering for the last seven consecutive years) and Aspects of Biochemical Engineering (has been offering for four years) (AICTE approved course for Undergraduate and Postgraduate students and FDP). He was awarded IAHE Akira Mitsue award 2008 and BRSI Malaviya Memorial award 2013 for his contribution in hydrogen research. He is a Fellow of Indian National Academy of Engineering (INAE); International Association for Hydrogen Energy (IAHE); Biotechnology Research Society of India (BRSI) ; West Bengal Academy of Science and Technology (WAScT); and Institution of Engineers (IE). He is the member of the editorial board of several International Journals. He is among the top 2% Scientists in the world issued by Stanford University 2023 and he holds third position in the area of 'Energy' in India.
