I am a remote sensing scientist and Associate Professor at the Geospatial Sciences Center of Excellence (GSCE), South Dakota State University (SDSU). My work bridges satellite data processing, geospatial modeling, and machine learning to address agricultural and environmental challenges. I lead and contribute to multiple NASA and USGS projects focused on soil moisture monitoring, crop classification, and climate resilience.
