Retired from the post of Director, Geological Survey of India (GSI)
Carried out geological and geo-technical investigations for several major infrastructure and hydropower projects across different regions. Notable among these is the Shimla Bulk Water Supply Scheme (a World Bank-funded project), construction of a two-lane traffic tunnel from Sanjauli to Dhalli in Shimla, parallel to the existing Dhalli tunnel, spanning approximately 160 meters.
He has conducted extensive studies for the Bokang Bailing Hydel Power Project (320 MW) in Uttarakhand, covering key components such as the 9.4 km Head Race Tunnel, underground powerhouse complex, tail race tunnel, dam/barrage, etc. Geological investigations encompass various hydel power projects in Kargil (Ladakh UT) and Uttarakhand, including the Jibagad Hydel Power Project (12 MW) in Dharchula. He has undertaken assessments for the Upper and Lower Nanti Hydroelectric Projects in Shimla district and the Upper Gaj Hydroelectric Project in Kangra district, Himachal Pradesh.
In addition to hydropower projects, he has conducted studies on iron ore formations across Sirmaur, Shimla, Mandi and Chamba districts in Himachal Pradesh. Base-metal investigations were also carried out in the Lohit district of Arunachal Pradesh and the Sataum area in Sirmaur district (H.P.). A geo-environmental appraisal for Environmental Impact Assessment (EIA) was undertaken over seven years across Una, Hamirpur, Shimla, Kinnaur and Lahaul-Spiti districts of Himachal Pradesh. Additionally, special thematic mapping of the Bandal Granitoid Complex and part of the Rampur Group was conducted in Kullu district for one year. His investigations have played a crucial role in assessing geological feasibility, environmental impact and mineral resource potential for various developmental projects.
