Present employment: Professor, Department of Applied Geology & Head, Central Research Facility; Indian Institute of Technology (Indian School of Mines) Dhanbad.
I am a micropaleontologist dealing with foraminifera (Unicellular eukaryotic hard test-bearing tiny marine organism) and calcareous nannoplankton (very small planktonic marine autotroph) along with geochemical and sedimentological proxies for understanding paleoclimate, paleoceanography, palaeogeography, hydrocarbon exploration, depositional environment, evolution, extinction, tectonism, biostratigraphy etc. I love finding them in sediments, seeing them under a microscope, measuring their different parameters, and unveiling hidden information. I have been doing this work since 2002. Teaching is my passion, and all my teachers have mentored me to do such a delightful job.

Postdoc Project Title: Integrating Machine Learning approaches to the Paleoclimatic datasets: Deciphering paleo-bottom water oxygenation history in ocean basins.
I am a paleoclimatologist and paleoceanographer specializing in marine paleoenvironmental reconstructions using foraminiferal and sedimentological proxies, and my current research is primarily concerned with isolating signals of the natural forcing of climate change from anthropogenic forcing, paleo-monsoon reconstruction, and deciphering the linkage between bottom water oxygenation and paleo-productivity. My PhD research focused on the East China Sea paleoceanography over the last 400 kyr and its linkages with the East Asian Summer Monsoon and Kuroshio Current variability. Using the sediment samples of Integrated Ocean Drilling Program (IODP) expedition 346 (Asian Monsoon) Site U1429 from the East China Sea, I generated the first 400 Kyr planktic/benthic foraminiferal record and reconstructed Kuroshio Current and Bottom water oxygenation variability in the East China Sea. Apart from my PhD research, I have also contributed to the research using the sediment samples on paleoceanography of the Japan Sea (IODP Expedition 346, Sites U1423 and U1426), Central Sooth Pacific (IODP Expedition 383, Site U1541), and to collaborative research on Soil quality. I am also associated with the Fiordland Assessment of Climate, Environment, and Tectonics (FACET) project proposal at the International Continental Scientific Drilling Program (ICDP).

I am a PhD student specializing in micropaleontology at the Indian Institute of Technology (Indian School of Mines) Dhanbad, India. I completed my M.Sc. Tech. in Applied Geology at IIT(ISM) Dhanbad in 2020, my current research focuses on unravelling the enigmas of past climates and paleoceanography.
Microfossils, particularly foraminifera, hold a deep fascination for me. My research utilizes these microscopic time capsules as invaluable tools to extract hidden clues from sedimentary archives. By employing a multiproxy approach, I aim to reconstruct past climate and paleoceanographic conditions, providing a comprehensive understanding of Earth's history.
Beyond academia, I maintain a strong passion for travel, seizing every opportunity to explore new destinations. Additionally, I find solace and inspiration in music and possess a keen interest in visual arts, specifically painting.

I am a Ph.D. student (JRF) specializing in gas hydrate research at the Indian Institute of Technology (Indian School of Mines) Dhanbad, Jharkhand, India. I completed my M.Sc. in Geology from the University of Lucknow, where my dissertation focused on the morphometric analysis of the Betwa River drainage basin using ArcGIS software.
My current research involves the characterization of gas hydrate-bearing sediments in the Mahanadi basin and the sequestration of CO2 by replacing CH4 in gas hydrate reservoirs. By studying the physical (porosity, permeability), chemical, and mechanical properties of sediments, I aim to understand the presence, concentration, and stability of gas hydrates. This work also examines the effects of gas hydrate-bearing sediments on the formation and dissociation mechanisms during combined depressurization and CH4-CO2 exchange methods. This process not only facilitates methane recovery but also contributes to CO2 sequestration, thereby helping mitigate global warming and meeting the rising energy demand sustainably.
Beyond academia, I am actively involved in cultural activities. I enjoy cooking, music, dance, and playing badminton, which keeps me balanced and engaged outside of my research pursuits.

I joined as a research scholar in the Department of Applied Geology at IIT(ISM) Dhanbad in June 2011 under the guidance of Prof. Ajoy Kumar Bhaumik. After being placed in the Geological Survey of India (GSI) in 2013, I converted my full-time PhD into part-time and completed my PhD in September 2020.
During my tenure at GSI, I carried out geological mapping in sedimentary terrains and conducted exploration work for coal and limestone commodities. I was primarily engaged in the coal exploration project in the Godavari Valley Coalfield, where coal is present in the Lower Kamthi and Barakar formations of the Lower Gondwana sediments.
Currently, I work as a Senior Geologist at the Geological Survey of India, State Unit: Telangana, Southern Region, Hyderabad. My research interests lie in Micropaleontology, Sedimentology, and Coal exploration.

My research interests encompass a diverse array of scientific fields, including sedimentology, sedimentary geochemistry, spectroscopy, micropaleontology, and petroleum geology. My broad research aim is to examine the sedimentary archives and microfossil communities of the Earth to elucidate depositional models, comprehend geological mechanisms, and make meaningful contributions to the domains of paleoclimate, paleoceanography, and applied micropaleontology in resource exploration.
 In addition to my scientific pursuits, I am passionate about sports, particularly cricket, and I have a keen interest in capturing the beauty of nature through photography, striving to blend my academic endeavours with my passions.Â

I am currently working as a PhD fellow at the IIT (ISM) Dhanbad. My research focuses on understanding Earth's paleoenvironments and geological processes through the study of microfossils and sediments, and it falls at the nexus of paleoclimate, sedimentology, and micropaleontology. In my PhD, I worked on Paleoclimatic and Paleoceanographic evolution in the western Bay of Bengal during Late Holocene: Evidences from foraminiferal and grain size distribution and also establish chronological framework by using AMS C14 dating of foraminifera. My work primarily focused on understanding the Benthic and planktic foraminiferal ecology in the Bay of Bengal and the reconstruction of the Indian monsoon during the last 1690 yr using benthic and planktic foraminiferal as a proxy. I was also associated with some projects outside of my PhD which gave me a fair knowledge of benthic foraminifera, diatom and pteropods as proxies for paleoclimate. This include Biostratigraphy and sedimentation rates of the Quaternary sediments of the Krishna-Godavari basin, Bay of Bengal using nanoplankton and planktic foraminifera as a proxy and Upwelling-related Oxygen Minimum Zone(OMZ) variations in the Salaverry Basin, offshore Peru evidence from benthic foraminifera.
