My key competencies lie at the intersection of three disciplines (Geospatial Science, Environmental Science, and Computer Science). I use geospatial technologies on a variety of land / environmental applications (Multi-Criteria risk assessment, Suitability analysis, Land-use/Land cover change analysis, GIS model development).
My doctoral dissertation was conducted at the Indian Institute of Technology, Dhanbad, where I studied the impacts of coal mining on water resources. In my research, I developed dynamic process-based spatially-explicit frameworks for vulnerability assessment of water resources due to coal mining activities.
March 2021 - Present: Studying the climate and environmental impacts of biochar use in Swedish agriculture through a life cycle and spatial perspective.
February 2019 - October 2020: Worked as a postdoctoral research engineer on developing sustainable bioeconomy strategies for France. I was responsible for the Research Objective 1 (RO1) of the Make Our Planet Great Again laureate project Cambioscop, at the Institut National des Sciences Appliquees (INSA), Toulouse, France. In RO1, I developed a spatial database for residual biomass resources currently available in France, and evaluated the environmental impacts of their current use through a life cycle assessment approach.
