I primarily work on water and wetland mapping and change analysis. In my PhD. Program, I mapped open surface water at state, country, and globe scales. I estimated Chlorophyll-a concentration in various lakes using Landsat and Sentinel images, and Chlorophyll-a field measurements. As a postdoc, I mapped sub-pixel water fraction (SWF) and generated vegetation classification of Arctic National Wildlife Refuge (ANWR), designed CONUS NWI update targeting tools, and developed methods for NWI rapid update.
