Varsha Ashok Aglawe has assumed charge as the 54th Director General (DG) of the Geological Survey of India (GSI), becoming the first woman to head the organisation in its 176-year history. She succeeds Asit Saha, whose two-year tenure as DG ended on 31 July 2026. Her appointment marks a historic milestone for an institution that began its work in 1851, when Thomas Oldham, a professor of geology from Trinity College Dublin, arrived in Calcutta to set up the survey.
Who Is Varsha Ashok Aglawe?
Aglawe is a distinguished geoscientist with more than three decades of professional experience. She began her career at the Indian Bureau of Mines before joining GSI in 1992. Over the years, she has served in GSI’s Central, Northern and Eastern regional offices as well as at its Central Headquarters in Kolkata, handling both scientific research and administrative responsibilities. Before this appointment, she was the Additional Director General and Head of Department for GSI’s Eastern Region in Kolkata.
Her scientific specialisation lies in palaeontology, the study of ancient life through fossils, and palynology, the analysis of pollen, spores and other microscopic organic particles. She has made notable contributions to the study of the Late Cretaceous to Palaeocene sediments, the K-T boundary, the geological horizon that marks the extinction of the dinosaurs, and the Satpura-Gondwana basins of Central India.
One of her landmark discoveries was reporting the Salbardi-Ghorpend area in Central India as a new dinosaur nesting site, a finding that added valuable detail to India’s prehistoric record. She has also collaborated with the University of Michigan Museum of Paleontology in the United States and represented India as part of the delegation to the PDAC 2023 mining convention in Toronto, Canada.
Beyond research, she led the establishment of a modern Palynology Laboratory at GSI’s Northern Region office in Lucknow and has steered several multidisciplinary geoscientific programmes across the country.
About the Geological Survey of India (GSI)
The Geological Survey of India is the country’s premier geoscientific organisation and one of the oldest scientific institutions in India. It was established in 1851, primarily to investigate coal deposits for the Railways, and is headquartered in Kolkata. It functions as a subordinate office attached to the Ministry of Mines.
GSI’s core mandate is to create and update national baseline geoscientific data through systematic geological mapping, mineral resource assessment and airborne and marine surveys. Its work underpins mineral exploration, so the agency plays a foundational role in locating the critical and strategic minerals needed for electronics, batteries, clean energy technologies and defence applications. The agency also contributes to public-good geoscience, including natural hazard studies of landslides and earthquakes, and to glaciology.
The organisation works through regional units spread across the country, each led by a senior officer, and operates specialised laboratories and training facilities. Its scientific workforce includes geologists, geophysicists, geochemists and other earth scientists.
GSI and Critical Mineral Security
India notified a list of 30 critical minerals in 2023, including lithium, cobalt, nickel, graphite, rare earth elements and others that are essential to modern manufacturing. To accelerate their discovery, the government launched the National Critical Mineral Mission (NCMM) in January 2025 with an outlay of ₹34,300 crore spread over seven years, covering exploration, mining, processing and recycling. Under the mission, GSI has been tasked with carrying out 1,200 exploration projects between 2024-25 and 2030-31.
These priorities shape much of GSI’s current work, since meeting the country’s clean energy and defence goals depends on reliable domestic supplies of these minerals.
Priorities for the New Director General
On taking charge, Aglawe said GSI would align its programmes with the government’s priorities on critical mineral exploration and mineral security. She outlined several immediate areas of focus for the organisation.
- Accelerating exploration of deep-seated and concealed mineral deposits through advanced geophysical investigations and fast-tracked exploration programmes
- Expanding offshore mineral exploration, particularly in India’s exclusive economic zone and the deep sea
- Strengthening laboratory infrastructure and promoting cutting-edge geoscientific research
- Advancing public-good geoscience, including natural hazard studies and glaciology
- Enhancing scientific publications and building capacity among young geoscientists
She expressed confidence that GSI, with its scientific expertise and expanding technological capabilities, is well placed to meet the nation’s growing demand for critical and strategic minerals while supporting sustainable resource development.
Why This Appointment Matters
The appointment is significant on more than one count. It breaks a 176-year-old glass ceiling in an organisation that has historically been dominated by male geoscientists, and it places a research scientist, rather than a career administrator, at the top of India’s national geological mapping agency. This is especially relevant at a time when the country is pushing to reduce its dependence on imported critical minerals such as lithium, cobalt and nickel, which are central to electric vehicles, batteries and renewable energy systems.
Aglawe’s background also brings a distinctive perspective. Her work in palaeontology and palynology links GSI to the study of India’s deep geological past, while her leadership experience across regional offices equips her to manage an organisation spread over the whole country. Her emphasis on building capacity among young geoscientists is expected to help refresh an ageing scientific workforce.
The appointment also signals the growing presence of women in leadership positions across India’s scientific institutions. In recent years, women have led organisations such as ISRO’s lunar missions and several national laboratories, and this appointment extends that trend to the country’s premier earth science body.
