Welcome to my website!
​
I am an Assistant Professor in the Department of Earth Sciences at the Indian Institute of Technology Gandhinagar, India. I specialize in foraminifera micropaleontology and paleoclimate reconstruction.
​
My research focuses on using Foraminifera—marine microfossils—as powerful tools for biostratigraphic correlation (from the Cretaceous to the present), paleo-bathymetry, and paleo-depositional reconstruction. Beyond their stratigraphic significance, I am particularly fascinated by how the chemistry of foraminiferal shells provides insights into past climates. By analyzing elemental ratios and stable isotopes, of these foraminifera tests we can reconstruct ancient ocean conditions and climate variations
Trained in marine micropaleontology, biostratigraphy, and foraminiferal geochemistry, I aim to apply these skill sets to explore the co-evolution of foraminifera and climate on deep-time scales.
