I grew up in the mountains of Nepal, witnessing the devastating impacts of earthquakes, landslides, wildfires, and floods. These experiences sparked my lifelong curiosity about natural hazards and motivated me to find ways to understand, predict, and reduce their impacts using science and technology.

My research sits at the intersection of geomatics, remote sensing, and artificial intelligence. I study how multiple hazards interact, how they can be monitored with satellite and geospatial data, and how AI can improve their modelling. I earned a Bachelor's in Geomatics Engineering from Tribhuvan University, followed by an MSc and PhD at the University of Twente, where my work focused on combining geophysical models, deep learning, and probabilistic approaches to better understand earthquake-induced landslides and floods.

I have collaborated with international institutions, including NASA's Jet Propulsion Laboratory, advancing remote sensing techniques for natural hazards and creating open datasets and courses on AI for hazard modeling. As an Assistant Professor at the University of Twente, I lead research projects on multi-hazard interactions, supervise MSc and PhD students, and teach courses on GeoAI and data-driven modeling.
