Ajay Kumar, Ph.D.

AJAY kumar

Assistant Professor, Biosystems and Agricultural Engineering





Research Interests

Kumar leads research in thermochemical conversion of biomass into fuels, chemicals and power. His primary research goals are to develop innovative experimental and modeling approaches to increase yields and efficiencies of biomass-derived products (drop-in fuels, chemicals and power), decrease the contaminant level, and improve reliability of the process models. His current projects include study on biomass characterization, reaction kinetics and fluidization of gasification, value-added utilization of biochar, synthesis and evaluation of biochar-based for syngas conditioning, and improving efficiencies of biomass pyrolysis.

“To best utilize our limited resources and maintain our standard of living, there is no alternative but to make ourselves less dependent on nonrenewable resources.”
