In nature, a rapid decrease in the population of threatened and commercially important medicinal and aromatic species by over-exploitation and habitat degradation is recorded. To overcome the pace of rarity, ecological surveys, ex-situ conservation, re-introduction in the natural habitats, and conversion of RET species into non-RET species is challenging work that requires a lot of effort. Therefore, by knowing importance of the conservation, my research is mainly focused on the following objectives:

•  Ecological and ethnobotanical studies of high altitude ecosystems/Western Himalayan Region.
• Domestication of important wild plant bioresources
• Ex-situ conservation of important medicinal plants in the ‘Plant Conservatory’ at CSIR-IHBT Centre for High Altitude Biology at Ribling (CeHAB), Lahaul & Spiti (H.P.)
• Characterization studies to find out elite germplasms
• Fresh snowmelt water harvesting technology for the dry temperate climatic conditions

• ASRB ICAR-NET 2007 (Forestry)
• Researcher (sponsored by World Pheasant Association, New Delhi), from 18.03.2005 to 14.09.2005 at GBPIHED     Mohal-Kullu (HP)
