The Master of Science (M.Sc.) program in Earth and Environmental Sciences had its inception in 1971. Over the years, it underwent several name changes: 1971-75: Geology and Mineralogy and Geological and Environmental Sciences in 1997. These transformations were a direct response to shifting national and global priorities, reflecting the dynamic nature of our academic pursuits.

The Department's faculty recruitment has been aligned with the evolving vision of the department, bringing in experts with diverse interests spanning environmental, engineering, and biological dimensions.

Research in this department spans various Earth science areas, including traditional geology and contemporary environmental issues. While we also address national concerns, our primary aim is to explore fundamental questions about Earth processes. Current research covers topics like Himalayan belt uplift, methane biogeochemistry, and analysis of rock deformation.​
