Professor Emeritus

Earth and Climate Science

Sedimentology, Sequence and Seismic Stratigraphy, Paleontology and Hydrocarbon exploration

Alok Dave earned his Master’s (1977) and Ph.D. in Geology (1982) from Banaras Hindu University. Prior to joining IISER Pune, he worked as a Geologist with Oil and Natural Gas Corporation (1983-2018) and retired as Executive Director from Mumbai in November, 2018.


Alok Dave specializes in micropalaeontology, carbonate sedimentology and sequence stratigraphy. Dr. Dave has carried out geoscientific studies of Indian petroliferous basins for 35 years and retired as Executive Director in 2018. In the early 1990s, he was involved with establishing lithostratigraphic classification of Indian petroliferous basins. He standardized core analysis techniques for implementation across all work centres of ONGC and was involved with the discovery of Dinosaur graveyard in Kutch. Dr. Dave authored books on Mesozoic Chrono-stratigraphy of Kachchh and Lexicon of Indian Stratigraphy. He served as chief editor of ONGC Bulletin beside editing Proceedings of XV Indian Colloquium on Micropaleontology and Stratigraphy, Seminar on Indian Petroliferous Basins (3 volumes), and Standard Laboratory Techniques for Geological Studies. He has successfully carried out collaborative projects with international oil companies like British Petroleum and Turkish Petroleum at their work centres. His recent work on Petroleum system modelling of Kutch-Saurashtra basin has established hydrocarbon resource base for future commercial production. Since 2005, he was actively associated with the sequence stratigraphic studies of the basins of western continental margin, including petroleum system modelling. He also successfully completed advanced Management course from IIM, Bangalore and Europe.
