I'm a PhD Candidate at the Department of Geography and the Environment at the University of Alabama, focusing on the fascinating intersection of Geographic Information Science (GIS), Remote Sensing, deep learning and Machine Learning to understand how rivers change over time.
My research focuses on river meander detection and classification using satellite imagery (including Sentinel-1 SAR) and deep learning workflows. I combine geomorphic metrics with spatial–temporal reasoning to analyze river dynamics, estimate channel characteristics, and support applications such as flood risk assessment, hydrological/hydraulic modeling, and environmental monitoring.
Before starting my PhD, I lectured at Kathmandu University, Nepal. I hold an M.Sc. in Geoinformatics from the University of Münster, Germany, and a background in geomatics engineering that continues to shape my approach to geospatial problem-solving.
- River Morphodynamics & Flood Resilience — Automated centerline and width extraction; meander detection/classification; flood mapping and scenario analysis.
- AI/ML for Earth Observation — Deep learning segmentation/classification, explainable ML, scalable cloud pipelines for SAR and optical time series.
- Hydrology & Hydraulics — Linking remotely sensed change with hydrologic/hydraulic models to improve inundation forecasting and hazard assessment.
- UAV & Field Integration — UAV multispectral/hyperspectral acquisitions; ground and boat‑based surveys (ADCP, YSI, ASD spectrometer, HYCAT) for calibration/validation.
