About me

I am a Geomorphologist, working on fluvial problematics. I am interested in learning the dynamics and morphology of rivers, effect of drainage congestion on flood inundation, and application of remote sensing to monitor soil moisture and stream flow. I combine mathematical theory, physical reasoning, field observations, and digital image analysis to recognize the necessary ingredients to model them.
