About
Me.

I’m a professional Engineering Geologist based in Nepal, specializing in landslides, debris flow, earthquakes, hazard assessment, disaster management, foundation analysis, and geology for roads and dams. With a strong background in geology and geotechnical engineering, I’m passionate about applying new technologies to solve real-world challenges. My goal is to advance engineering geological research in Nepal, support sustainable development in the Himalayas, and promote education as a driver of progress and poverty reduction.
