Dr. Wulamu's research focuses on environmental impacts of land cover and land use (LCLU) and climate change, with particular attention to water resources and agriculture. He develops algorithms to characterize the changes to Earth's land cover and integrate remote sensing observations with model-based approaches to understand the impacts of climate and land use changes on the water and energy cycles and ecosystems from local to global scales. As a geo-environmental scientist specializing in remote sensing and GIS applications, he is interested in developing new methods that improve the information content of satellite data for improved LCLU mapping. To this end, he uses multispectral, hyperspectral, and active microwave (SAR/PolInSAR/InSAR) and field observations to map crops, invasive plants, minerals and InSAR data to monitor land subsidence from anthropogenic activities, which are unified by a central theme: monitoring the impacts of climate and land-use changes on the environment using remote sensing and GIS as the primary tool. Examples of ongoing or recent projects in Dr. Wulamu's lab include (1) climate change and precision agriculture: monitoring plant responses to water and ozone stress using field, airborne (UAV/UAS, manned aircraft) and satellite hyperspectral remote sensing, (2) impacts of land-cover and land-use change (LCLUC) on water quality under various scenarios of future climate change and land use modifications, (3) applications of InSAR/DInSAR/LiDAR in predictive modeling of geological hazards (e.g., landslides), and (4) integrated use of hyperspectral and SAR data fusion in minerals and plant species detection. Currently, he is involved in NASA's Air Quality Applications Science Team (AQAST), and NASA's next mission that will study atmospheric composition, TEMPO (Tropospheric Emissions: Measurement of Pollution), which is scheduled to be launched in 2019. He has authored over 30 peer-reviewed journal publications, one book chapter, and presented more than 30 conference papers and workshops.
