I use satellite synthetic aperture radar (SAR) to understand when and where mountain snowpacks melt — a critical signal for water resources, flood forecasting, and climate science. My dissertation built a global, 80-meter resolution dataset of snowmelt runoff onset timing from a decade of Sentinel-1 imagery (~3.9 million scenes, 2015–2024), covering ~150 mountain ranges worldwide.


I recently finished my PhD in Civil & Environmental Engineering (Data Science option) at UW and am now a postdoctoral scholar in the TACO Lab, where I'm integrating NASA NISAR L-band data into our Sentinel-1 workflows and building cloud-native geospatial processing pipelines. I also regularly teach Geospatial Data Analysis in Python (CEE 467/CEWA 567) at UW.

Global Snowmelt Runoff Onset Dataset

A decade (2015–2024) of annual snowmelt timing across mountain ranges worldwide, derived from ~3.9 million Sentinel-1 SAR scenes at 80 m resolution. Validated against 900+ weather stations.
