Participation in research and instrument projects:
-------------------------------------------------
- Member of the COSMOS collaboration, and in particular:
– principal responsible for the XMM-COSMOS project (PI: G. Hasinger);
– member of the core-team of the C-COSMOS project (PI: M. Elvis);
– associated scientist of the z-COSMOS collaboration (PI: S. Lilly);

- Member of the SSC (Survey Science Center) consortium of the XMM-Newton satellite;
- Member of the eROSITA (PI: P. Predehl) consortium, a german-russian X-ray telescope expected to be launched in late 2013; it will provide the first sensitive (a factor of ∼ 30 deeper than ROSAT) all sky survey in the soft and hard X-ray bands. I am part of the AGN WG (co-chair) and responsible for assessing the sensitivity of the survey for point-like sources.
- co-Investigator of 4MOST (PI: R. de Jong), one of the two projects selected for concept study for future multi-object spectrograph at ESO, and designed to provide high resolution spectroscopy for ∼90% of eROSITA sources observable by ESO telescopes. I am part of the AGN working group and I contributed to put together the eROSITA and AGN science case. I am also responsible to deliver the AGN mock catalog to be used to test different instrument setups (in terms of resolution, numbers of fibers, FOV etc.) and therefore to choose the final design of the instrument. I am also co-investigator of the SPIDERS proposal (SPectroscopic IDentifications of ERosita Sources), selected as part of the After Sloan 3 call for proposal to use the APO telescope of Sloan for follow-up of eROSITA sources from 2014 on.

Outreach experiences:
--------------------
early in my career, I was invited to my former high school to present the programs of the Astronomy courses at the Bologna and Padova universities.
One of the earliest results in my scientific career (the lack of significant evolution with redshift in the metal abundances of AGN, Brusa et al. 2005) has been the subject of a press release from the Chandra X-ray Center (http://chandra.harvard.edu/photo/2005/felines/).
Other results that I have obtained within the COSMOS collaboration and in particular the XMM-COSMOS project, have been brought to the general public through press releases and media interviews (e.g., http://www.eso.org/public/news/eso1124/, ESO press release of Allevato et al. 2011).
I also participated in the MPE Open day of public outreach, helping with the organization of events for young kids.

Research track record
---------------------
I have played a major role in the last 10 years in the planning, execution, and scientific
exploitation of several leading X-ray and multi-wavelength surveys (HELLAS2XMM, COSMOS, CDFS, among others), which led to world-wide recognized results (see list of publications).
Most of my work in the past years has been devoted to data reduction and analysis of X–ray data and multi-wavelength catalogs in the COSMOS field. I have been involved in the data analysis and reduction of XMM-Newton observations, leading, among others, to publications on the X-ray logN-logS (Cappelluti, Brusa et al. 2009), and on the multi-wavelength properties of X-ray sources (Brusa et al. 2007, 2010). My scientific interest in the COSMOS field (extended also to the deep observations in the Chandra Deep Fields, CDFS and CDFN) was mainly the search, the study and the characterization of the most obscured sources at z∼ 1− 2 and their host galaxies, both directly selected in the X–rays (Brusa et al. 2003, Brusa et al. 2005, Brusa et al. 2007; Brusa et al. 2009b; Brusa et al. 2010; Mainieri et al. 2011) or revealed through stacking analysis in infrared selected samples of candidate obscured AGN (Brusa et al. 2002, Fiore et al. 2008; 2009; Luo et al. 2011). More recently, I focused my research on the high-redshift X-ray selected population (Brusa et al. 2009a, Civano, Brusa et a. 2011). By means of studying average spectral properties of deep fields sources, I was also able to exclude a significant evolution in the equivalent width (and therefore in the iron abundance) of AGN with cosmological redshift (Brusa, Gilli & Comastri 2005; recently extended in the work by Chaudhary, Brusa et al. 2010, 2012).
