Welcome to the Geospatial Analysis for Environmental Change (GAEC) Lab!

We are a group of dynamic geospatial scientists working on quantifying space time patterns of environmental change using remote sensing, spatial analysis and graph theory at sub-continental to continental scale.

Research Interests

Surface Water

Understand surface water dynamics

Remote Sensing

General research topics related to remote sensing

Flooding

Map flooding events using remote sensing

Climate

Understand the impacts of climate drivers on water systems

Environmental Justice

Examine the impact of environmental risks on vulnerable communities
