He is a Full Professor in Astrophysics at the Department of Engineering of the University of Basilicata, where he has taught courses on Satellite Remote Sensing and General Physics since 1997. He has been the coordinator (or PI) in several national and international projects funded by EC (FP6-IST, FP6-INTAS, FP6+FP7 GMES, Horizon, Erasmus+, etc.), the International Space Science Institute, and NATO (Science for Peace). His research activity has been focused on the development of new satellite sensors and techniques for forecasting, monitoring, and mitigating natural, environmental, and technological hazards. In this context, he proposed the original RAT (now RST) change detection approach, which is today successfully used in a large spectrum of applications. He is the author or co-author of more than 200 papers on international journals, scientific books and international conference proceedings (https://orcid.org/0000-0003-3875-7909).
