Another major thrust of his current research is efficient conversion of biomass to liquid fuel and maximizing liquid fuel from a given quantity of biomass. He is also involved in modeling to find the role of biofuels vis-a-vis other solar energy derived alternatives to propel an entire transport sector in a solar economy. Biomass to Liquid Fuels Website
The group is also involved with developing efficient separation processes. Currently methods to synthesize and identify energy efficient distillation configurations for multicomponent separation are being developed. Additional effort is being devoted to develop optimal methods for membrane separation processes. Separations Group Website
He has a broad experience in hydrogen production and purification technologies. This has evolved from his earlier activity in developing integration steps within coal gasification combined cycles for power as well as syngas generation.
His research interests also include basic and applied research in process development, gas liquefaction processes, cryogenics, and thermodynamics.
