I have always worked on high energy astrophysics: my PhD thesis at SISSA, Trieste, dealt with interacting binary systems. After a postdoc at NASA/GSFC, I was involved in the calibration of the high energy experiment PDS aboard the BeppoSAX satellite, and then in its data exploitation . Since then I work at the Astrophysics and Space Science Observatory (formerly TeSRE and IASF) in Bologna, Italy, analyzing X-ray data from celestial sources (mainly compact galactic objects) , developing software for data analysis, and participating in the development of future high energy missions.
