Mandakolathor Subrahmanya Srinivasan earned his BSc and MSc degrees from Banaras Hindu University (BHU) with highest honours. Thereafter, he joined as Lecturer in the Department of Geology at BHU (1960); proceeded to New Zealand (1963) as a British Commonwealth Scholar and received PhD (1965) from the Victoria University, Wellington. He visited the British Museum (Natural History), London (1968-69) and examined its foraminiferal type collections from different expeditions. He was Visiting Scientist at the Graduate School of Oceanography, University of Rhode Island, USA (1972-74, 1979-81), where he taught and carried out researches on various aspects of oceanic biostratigraphy and paleoceanography. He also participated as a Ship Board Scientist in the Deep Sea Drilling Project Leg-90 on board the D/V Glomar Challenger in the South Pacific (1981-82). He was Head of the Department of Geology, BHU (1984-86) and Director, Academic Staff College (1991-93). After his superannuation (2001), he was INSA Honorary Scientist (2001-03) and INSA Senior Scientist (2003-08). In recognition of his distinguished services, BHU honoured him by appointing Professor Emeritus.
Academic and Research Achievements: On returning to India, Srinivasan established micropaleontology laboratory at BHU and initiated both teaching and research programmes in micropaleontology and paleoceanography. His active participation in Deep Sea Drilling Programme (DSDP) and other international scientific cruises, boosted up deep sea research in the country. Srinivasan's researches directed on planktic foraminiferal biochronology employing Graphic Correlation method provided basic clues to the studies on evolutionary trends in this group. His integrated approach combining multiple microfossil biostratigraphy and chemostratigraphy led to trace the timing of opening and closing of ocean gateways and their impact on ocean circulation and climate. He authored over 180 research papers, wrote two books and edited few publications. During his long career spanning almost 48 years, he motivated and inspired a whole generation of Indian and overseas students, including 14 PhD students.
Other Contributions: Srinivasan established a reputed Micropaleontology Research Centre in India to carry out studies on deep sea cores. Some of his other notable contributions relate to the Neogene of Andaman-Nicobar Islands and evolution of Asian Monsoon. He served as Executive Member of the Regional Committee on Pacific Neogene Events, and Leader of the International Working Group on Equatorial Pacific Neogene Chronostratigraphy. He was also INSA Council Member (1993-94).
Awards and Honours: Professor Srinivasan received the UGC National Lecturer Award (1984-85), the First Malavia Memorial Trust Senior Academic Award by BHU (1986), Professor L Rama Rao Gold Medal (1988), Platinum Jubilee Lecture of ISC (1991), Hari Om Ashram Trust Award by UGC (1994), Swami Pranavanad Saraswati Award (2001), Professor Birbal Sahni Memorial Lecture Award (2002) and Dr. H. N. Siddiqui Memorial Lecture (2008). He was elected Fellow of the Indian Academy of Sciences, Bangalore, National Academy of Sciences (India), Allahabad and the Academy of Sciences for the Developing World (TWAS).
