  1. Studied vestured pits and helical thickening in vessel in 240 species of wood using Scanning Electron Microscope and developed a classification of vestured pits and helical thickening in relation to it’s function and its Utility in seasoning and preservative treatment of wood
  2. Developed sustainable tapping methods for gum in Sterculiaurens (commercially known as gum karaya), oleo-gum-resin from Commiphora weightii (commercially known as Guggal) and other species
  3. Promoted safe and efficacious formulations for PHC (out of 435 LHT documented for 61 prioritized health conditions) for Human in 13 states. Established 21,454 HHGs in 451 villages, trained 2083 Women Village Resource Persons (VRPs). Intervention impact analysis indicates 70 to 100% cure for PHC and 88% reduction of family expenditure for PHC
  4. Documented Ethno-veterinary practices from 24 locations from 10 states, established that 353 out of 441 formulations documented are safe and efficacious, 15 remedies have gone through clinical observation studies. Demonstrated that 87.86% reduction in the antibiotic residue in the milk when EVP is used. Farmer’s expenditure on treatment of animal health conditions is reduced by 94%
  5. Trained 863 vets, 17000 farmers, 520 VRPs to use EVP and thereby disseminated EVP in 15 states and 30 milk Unions.
  6. Organized international exchanges, seminars and workshop
  7. 44 Publications, 5 books 5 edited volumes
  8. 8. Developed collaborations with organisations like NDDB, AMUL, TANUVAS and other Veterinary Universities, State veterinary councils, Natural Livestock Farming Netherlands, Ethiopia and Uganda

I am interested to engage with PhD students, young people interested in designing and executing innovative educational and outreach programs related to:

• Functional anatomy, wood
• Gums and resin secretion and sustainable tapping
• Development of PHC products for human and animal based on LHT
