Hey there.

I’m a hydrogeodesist by training, currently pursuing a Ph.D. in Geosciences at Virginia Tech, USA. My doctoral research leverages satellite geodesy, radar remote sensing, physics-based models, and artificial intelligence to address and advance our knowledge on global challenges associated with groundwater and geohazards. This website offers a glimpse into my research, what I study, how I study it, and why understanding Earth’s hidden water matters.
