Roberto Colombo is professor of Remote Sensing at the Department of Environmental Sciences, University of Milano Bicocca. The main research interest is to develop remote sensing tools for quantitative estimation of land surface properties. He works with a wide range of Earth Observation data at different scales and geophysical methods, assimilating multi-source, multi-spectral and multi-temporal remote sensing data, from field spectroscopy to satellite level for modelling terrestrial and environmental dynamics, with focus on vegetation fluorescence and snow properties. Current activities include space mission concepts and definition, airborne campaigns and field cal/val strategies, engineering and design of proximal remote sensing instruments, algorithm development, environmental modelling and new applications.
