My research program is devoted to develop superior sorghum lines to be used as lignocellulosic feedstock for biofuel production and to discover genes/alleles associated with traits that confer superior biomass yield through the use of molecular and genomic technologies. The genetic knowledge generated in my research program will be applied to sorghum but could be utilized for the genetic improvement of other crops as well.

Sorghum was selected based on the genotypic and phenotypic variation of the species, and the high productivity potential as a biofuel source. Sorghum can be used to produce ethanol from grain, stover, sugars accumulated in the stems (sweet sorghums) or as a dedicated lignocellulosic biomass crop (particularly photoperiod-sensitive types). The sorghum breeding program at ISU includes all sorghum types and uses described above, prioritizing photoperiod-sensitive materials.
