Environmental engineer working where satellite remote sensing, hydrology and machine learning meet. I build Earth-observation workflows in Google Earth Engine and Python: mapping surface water and wetlands, tracking change over decades, and turning the results into decision support for water management.
- 🛰️ Focus: wetland and surface-water change, land-cover classification, change detection, water-allocation modelling
- 🌍 Live demo: Global wetland water-area trends, 1984–2025, an interactive map of 40 years of Landsat trends for ~600 lakes and wetlands
- 📄 Latest paper: Scenario-driven decision support system for assessing water balance, Journal of Hydrology (2026)
- 🔎 Peer reviewer for Journal of Environmental Management, Agricultural Water Management and Journal of Hydrology
