Subsequently he was posted at EPE division at DGCO, New Delhi where, as an Engineering Geology expert, he was engaged in geological and geotechnical appraisals of mega hydropower projects located in India, Nepal and Bhutan. At the National Mineral Exploration Trust (NMET), he accelerated mineral exploration activities. He has authored over 47 geotechnical reports and contributed to significant reforms in the mineral sector as Director (Tech) in the Ministry of Mines. Presently, Sh. Pradeep Singh is holding the prestigious position of NMH1A, DDG, IT in GSI. He is also the chairman of the Technical & Cost Committee (TCC-II) of the National Mineral Exploration Trust.

Shri. Asit Saha took charge as the 53rd Director General of the Geological Survey of India on July 27, 2024. A Gold Medalist with an M.Sc. in Geology from the University of Calcutta, he joined GSI in 1992. Saha's expertise spans Geoinformatics, Mineral Exploration, and Geochemical Mapping. He played a pivotal role in the GSI-BRGM project and the development of the Online Core Business Integrated System (OCBIS).

He actively participated in conceptualization, documentation, implementation and rollout of the state-of-the- art Online Core Business Integrated System (OCBIS) in GSI, as a logical and much needed upgrade of GSI digital infrastructure.
