Personal Statement
Growing up in Bangladesh and witnessing the first-hand effect of different hazards and the way the communities recover had led me to question how I can make it better on a holistic level. I did both my BSc and MSc in Disaster Science and Management from University of Dhaka. As an eager mind who loves to explore the roles of spatial analysis, I have a predilection to grab any opportunity that involves research regarding burgeoning of it. My goal is to continue pushing the limits of climate vulnerability and disaster assessments with geospatial analysis and remote sensing applications.
