Anil Kumar Gupta (born 1960) is an Indian geologist and academic. His research focuses on paleomonsoon dynamics, paleoclimatology, and paleoceanography, with an emphasis on reconstructing past variability of the Indian Summer Monsoon using micropaleontological and sedimentary proxies.
Gupta served as a Director of the Wadia Institute of Himalayan Geology from 2010 to 2017 and was Head of the Department of Geology & Geophysics at Indian Institute of Technology Kharagpur (IIT Kharagpur) from 2006 to 2009.
He was awarded the TWAS Prize in Earth Sciences in 2010 for his contributions to palaeoclimatology.

At IIT Kharagpur, he served as Head of the Department of Geology and Geophysics from 2006 to 2009 and later as Head of the Centre for Oceans, Rivers, Atmosphere, and Land Sciences (CORAL) from 2018 to 2021.
Gupta served as Director of the Wadia Institute of Himalayan Geology from 2010 to 2017.
His career has included additional academic and research affiliations, including international fellowships and research associate positions.
Awards
Gupta received the Young Scientist award from the Indian Science Congress Association (ISCA) in 1990. He was awarded a fellowship from the Japan Society for the Promotion of Science (JSPS) to conduct research at Shimane University. In 2001, the National Research Council (NRC) awarded him a Senior Research Fellowship Award to work at the National Oceanic and Atmospheric Administration (NOAA) Laboratory in Boulder, Colorado. Gupta received the TWAS Prize from the World Academy of Sciences (TWAS) in 2010. He was granted the J.C. Bose National Fellowship by the Indian Department of Science and Technology (DST).
His honors and achievements include being
Elected as Fellow of the Indian Academy of Sciences, Bangalore (FASc), India, 2008.
Awarded the UNESCO-TWAS Prize of The World Academy of Sciences, Italy, 2010.
Research
Gupta has contributed to the fields of micropaleontology, paleoclimatology, and paleoceanography, with a focus on the Indian monsoon system. He assisted in the publication of the Inventory of Glacial Lakes of Uttarakhand.
Gupta's work focuses on decadal to millennial-scale changes in the South Asian and Indian monsoon systems and their teleconnections with climatic shifts in the North Atlantic. His research is based on proxy records from the Arabian Sea, the Indian Himalaya, and the Ganges Basin. He and his team have studied foraminifera microfossils from the Arabian Sea to identify both short- and long-term shifts in the South Asian and Indian monsoons during the Quaternary. His work links Asian and Indian monsoon failures to societal collapses, human migrations, and changes in agricultural practices in South Asia during the Holocene epoch. His recent studies from the Himalayan and Ganges Basin lakes have indicated a long arid phase between 4,350 and 2,900 years BP that led to the displacement of Indus settlements and a major change in agricultural practices, including land use patterns.
To understand the history of Indian monsoon variability, as well as changes in the Indian Ocean, Gupta has studied benthic and planktic foraminifera, as well as their stable isotopes from Ocean Drilling Program (ODP) cores. His research includes the first identification of the Indian Ocean Dipole in a paleoclimate record and the documentation of Bond cycles in the paleorecord of the Indian monsoon over the Holocene. To understand regional precipitation, Gupta studied lake deposits and cave carbonates (speleothems) across the Indian landmass. His work produced the longest speleothem record from India, which revealed major shifts in the intensity of the Indian monsoon.
