Dr. Das has worked in research, outreach and teaching related to biomass management for over 20 years, focusing on processes for value addition and new product creation. Focus areas of his work include bioconversion and thermochemical conversion of biomass to energy and chemical feedstocks, and development of an integrated biorefinery. This includes pyrolysis, gasification, anaerobic digestion, and composting for conversion of waste to energy or products. Through his research, he has authored or co-authored 54 peer reviewed journal articles, six book chapters, 106 conference papers, and he has participated as principal investigator (PI) or Co-PI in over 50 federal, state, or industry funded projects (totaling over $4 million). He teaches senior-level engineering process design and environmental engineering courses at the University of Georgia.
