Research Interests

My goal in biomass production research is to find the best perennial grass species, develop the best management practices for environmentally friendly sustainable biomass production for biofuels production. My current research interests are:

• Evaluation of perennial grasses for cellulosic biomass feedstock production
• Native warm season grass cultivar/germplasm evaluation for biomass production
• Development of the best agronomic management practices including establishment, fertility, and harvest for sustainable biomass feedstock production
• Determination of the biomass production impact on root biomass and carbon sequestration
