Relevant Experience
He has a PhD thesis in space image processing and an extensive experience in remote sensing data processing and image quality techniques both on ground segment (geometrical corrections and quality) and space segment (payload integration: radiometric corrections and instrument performance). He has been involved in Helios 2 AIT On-Ground test (Thales-Alenia Space) and in Helios image ground segment (EADS Astrium). During these two missions, he was assigned to AIT imaging performance tests (Thales) and to image exploitation on a ground segment (Astrium). He is now working in EUMETSAT since five years in the Real Time Services and Systems Operations (RSO) as Instrument Data Processing Engineer on MSG and EPS operations. He was deeply involved in the MSG3 Image Commissioning.
