Early life and career

Gupta was born in the Budaun district of Uttar Pradesh in 1960. He graduated with a Bachelor of Science with Honours (B.Sc. Hons) from Aligarh Moslem University in 1980 and a Master of Science (M.Sc.) from Banaras Hindu University in 1982. From 1982 to 1987, he served as a research fellow at the Banaras Hindu University. He worked as a lecturer at the Indian Institute of Technology (IIT), Kharagpur between 1987 and 1990.

Gupta has received many awards for his work in Geology, including the TWAS Prize from the World Academy of Sciences (TWAS), Trieste, in 2010. In 2012, he was granted the J.C. Bose National Fellowship by the Department of Science and Technology (DST), New Delhi, India. In 1990, the Indian Science Congress Association (ISCA) honored him with the Young Scientist Award (YSA). In 2001, the National Research Council (NRC) awarded him a Senior Research Fellowship Award to work at the National Oceanic and Atmospheric Administration (NOAA) Lab in Boulder, Colorado. In 1999, Gupta received a Japan Society for the Promotion of Science (JSPS) Fellowship to work at Shimane University, Matsue, Japan. [1]

With a focus on the Indian monsoon, Gupta has contributed to the fields of micropaleontology, paleoclimatology, and paleoceanography, with special reference to the Indian monsoon system. Gupta assisted in the publication of "Inventory of Glacial Lakes of Uttarakhand." [4] Over 176 of his articles have been published in journals such as Nature, Science, Nature Geoscience , Scientific Reports , Geology, Geophysical Research Letters , and Palaeo3.

Gupta's work focuses on decadal to millennial scale changes in the South Asian/Indian monsoon system and their teleconnection with climatic shifts in the North Atlantic based on proxy records from the Arabian Sea, Indian Himalaya, and the Ganges Basin. He and his team have studied microfossil foraminifera from the Arabian Sea to identify short and long-term shifts in the South Asian/Indian monsoon during the Quaternary. [5] [6] [7] His work links Asian/Indian monsoon failures to societal collapses, [8] [9] human migrations, and changes in agricultural practices in South Asia during the Holocene. His recent studies from the Himalayan and Ganga Basin lakes indicate a long arid phase during 4,350-2,900 years BP that led to the displacement of Indus settlements and a major change in agricultural practices, including land use patterns. [10]

To understand the history of Indian monsoon variability, as well as oceanic changes in the Indian Ocean, Gupta has studied benthic and planktic foraminifera, as well as their stable isotopes from Ocean Drilling Program (ODP) cores. [11] His research includes the first identification of the Indian Ocean Dipole in a paleoclimate record and the documentation of Bond cycles [12] in the paleorecord of the Indian monsoon over the Holocene. To understand precipitation variations in the region, Gupta has studied lake deposits and cave carbonates (speleothems) from different parts of the Indian landmass and has produced the longest speleothem record from India, revealing major shifts in the intensity of Indian monsoons for the first time.
