My research explores the dynamic interplay between climate, environment, and life through geological time. Working in the biodiversity-rich yet under-studied northeastern region of India, I seek to understand how past and present climate variations shape ecosystems and influence human–environment interactions. My primary research expertise lies in micropalaeontology, palaeoclimatology, and sequence stratigraphy. I have conducted extensive research on palaeoclimatological reconstruction, focusing on periods of significant climatic transitions (equivalent to present day global warmimng) such as the Paleocene–Eocene Thermal Maximum, Early Eocene Climatic Optimum, and the Eocene–Oligocene Transition using multiproxy analysis including foraminiferal assemblage, geochemical proxies and sedimentological input. Complementing my palaeoclimate research, I investigate foraminiferal assemblages along the east coast of India as sensitive bioindicators of marine pollution. By analyzing changes in foraminiferal morphology, abundance, and diversity across pollution gradients, my goal is to standardize foraminifera-based monitoring protocols for assessing coastal ecosystem health. This work bridges micropaleontology with environmental monitoring, contributing to sustainable coastal management practices.
Other than the climatic aspect, I use foraminifera as a tool for age determination of the rock through biostratigraphy as well as for sequence stratigraphic analysis
Through interdisciplinary collaboration, I aim to foster research that connects palaeoclimate records, ecological responses, and sustainable futures. I believe that knowledge dissemination must be structured and adaptive—integrating field experiences, storytelling, and mentorship to inspire critical thinking among students, colleagues, and local communities.
