Dr. Jisung (Geba) Chang holds a Ph.D. in Geo-Information from the Technion – Israel Institute of Technology (2017) and is currently a Senior Postdoctoral Fellow at the USDA-ARS Hydrology and Remote Sensing Laboratory in Beltsville, MD. His research integrates polarimetric SAR and multi/hyperspectral with advanced machine/deep learning approaches to improve agricultural and environmental informatics. He has developed novel models for biomass estimation, crop yield prediction, and SAR-based vegetation indices such as the Normalized Polarimetric Radar Vegetation Index (NPRVI). Dr. Chang is a Senior Member of IEEE and an active member of AGU, GRSS, and ISPRS. His contributions have been recognized through invited editorial roles, leadership in special issues, and broad citations across remote sensing and agricultural science communities.
