Research Interests:
Biomass-Based Fuels:
Most Waste-to-Energy technologies are still at an emerging stage with a lot of room for innovation. Process optimization requires fundamental research on each one of the conversion processes. An important step involves experimental research to identify chemical and metabolic pathways that will be essential to maximize conversion yields of biomass to biofuels for both thermochemical and biological platforms.
