Andrea is an X-ray astronomer and currently the Director of the Astrophysical and Space Science Observatory of the National Institute of Astrophysics in Bologna, Italy.
During his career, he has worked on the X-ray observations of Active Galactic Nuclei (AGN) and population synthesis models for the X-ray background.He has been deeply involved in most of the X-ray surveys carried over by several missions and the follow up multiwavelength observations performed with both ground and space based observatories.
His present scientific activity is concentrated on the search for and the characterization of highly obscured, Compton thick AGN in ultra-deep X-ray surveys and the nature of the first accreting sources in the early (z > 6) Universe.
Andrea is a co-chair of the Topical Panel on high redshift AGN and a member of the WFI Science Team and Consortium Board.
