With a focus on the Indian monsoon, Gupta has made contributions to the fields of micropaleontology, paleoclimatology, and paleoceanography with special reference to the Indian monsoon system. He carried the publication of Inventory of Glacial Lakes of Uttarakhand.[2] More than 176 of his articles in high-impact journals have been published in journals like Nature, Science, Nature Geoscience, Scientific Reports, Geology, Geophysical Research Letters, and Palaeo3 . In order to understand the history of Indian monsoon variability as well as oceanic changes in the Indian Ocean, Gupta has a long history of scientific acumen and research nuances[peacock prose]. He has studied benthic and planktic foraminifera as well as their stable isotopes from Ocean Drilling Program (ODP) cores.[3] At time scales ranging from decadal to millennial and orbital, he has made contributions to the knowledge of the past behavior of the Indian monsoon system and ocean circulation. His research includes the first description of the Indian Ocean Dipole in a paleo record and the documentation of Bond cycles[4] in the paleo record of the Indian monsoon over the Holocene.
To understand precipitation variations in the region, Gupta has initiated new research projects on lake deposits and cave carbonates (speleothems) from different parts of the Indian landmass. He has produced the longest speleothem record from India that documents important shifts in the intensity of the Indian monsoon for the first time.[5] At the Indian Institute of Technology in Kharagpur, he has created laboratories that meet international standards and had the equipment necessary to do high resolution paleo-monsoonal research utilizing marine sediments, lake deposits, cave carbonates. Prof. Gupta has mentored 20 Ph.D. students.
Gupta was born in Budaun district of Uttar Pradesh in 1960. In 1980 he completed his Bachelor of Science with Honors (B.Sc. [Hons]) from Aligarh Muslim University, and in 1982 he pursued Master of Science (M.Sc.) from Banaras Hindu University.[3]
Since 2003, Gupta has been working as a professor in the Department of Geology and Geophysics at the Indian Institute of Technology (IIT) Kharagpur. Prior to that, he worked as a lecturer (1987–1990), Assistant Professor (1990–1999), and Associate Professor (1999–2003) in the same institution. He was also the department's head during 2006–2009.In 2010, he became the Director of the Wadia Institute of Himalayan Geology, Dehradun, and served it for seven years.Thereafter, he retired from the post of Professor in the Department of Geology and Geophysics at the Indian Institute of Technology Kharagpur in March 2025.

Gupta's work focuses on decadal to century and millennial scale changes in the South Asian/Indian monsoon and their teleconnection with climatic shifts in the North Atlantic based on proxy records from the Arabian Sea, Indian Himalaya and Ganga Basin. He and his team have made new insights in utilizing microfossil foraminifera from the Arabian Sea to identify both short- and long-term shifts in the South Asian/Indian monsoon during the Quaternary.[8][9][10] His studies have made advances in linking Asian/Indian monsoon failures to societal collapses,[11][12] 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 pattern.[13] Furthermore, his studies foresee more extreme events in the Asian/Indian monsoon behavior in future as the Earth will warm owing to both natural forcing and human intervention. These research findings provide means to better perform climate modelling efforts.
Gupta is known for his research work that has societal impact. He has about 176 peer-reviewed research papers in high impact factor journals including Nature, Science, Nature Geoscience, Nature Scientific Reports, Geology and Geophysical Research Letters, etc.[14] He has published a book entitled "Neogene Deep Water Benthic Foraminifera from the Indian Ocean – A Monograph" on Nova publishers.
