Hamed Alemohammad is an Associate Professor in the Graduate School of Geography and Director of the Center for Geospatial Analytics at Clark University. He is a technical leader and interdisciplinary scholar with extensive expertise and knowledge in remote sensing, earth science, and artificial intelligence (AI). His research interest lies at the intersection of geospatial analytics/AI and geography to use observations to better understand the changing Earth system.
Hamed has been the PI for several projects focused on developing novel AI models for multispectral, microwave and synthetic aperture radar (SAR) satellite observations. In recent years, his research has been focused on development and application of geospatial foundation models. He also serves as a member of the Technical Advisory Committee of Digital Earth Africa.
Prior to Clark University, Hamed was the Chief Data Scientist and Executive Director at Radiant Earth where he established and led the development of Radiant MLHub - the open-access repository for geospatial training data and AI models. Hamed received his Ph.D. in Civil and Environmental Engineering from MIT.
