Current responsibilities:

  • Biochemical studies on sucrose accumulation in sweet sorghum for efficient ethanol production in sweet sorghum (NFBSFARA project upto 2015 as a PI)
  • Studies on the therapeutic properties and establishing sorghum as a functional food (DBT project as a PI upto 2014)
  • Research responsibilities on sorghum health foods in sorghum in XII plan
  • Studies on 1st and 2nd generation fuel ethanol from sweet sorghum

Recent 3 major contributions:

  • Contributed for the release of the first public sector hybrid of sweet sorghum CSH 22 SS and variety CSV 24SS after establishing the commercialization of use of sweet sorghum cane for fuel ethanol production
  • Developed process for making poha (beaten sorghum) from sorghum using rice flaking machine , extruded sorghum (pasta and vermicelli)and preconditioning of grain for the preparation of pops
  • Developed 30 food recipes based on sorghum for rural and urban population
  • Developed a sensitive analytical reagent (BSA Benzidine conjugate) to quantify protein precipitable polyphenols in plants. The reagent was stable and tested efficiently in sorghum, tobacco, cocoa, coffee and neem.
