Francesco Tombesi is a post-doc scientist in the Astrophysics Science Division (ASD) at NASA/GSFC who was a recipient of an ASD peer award in August 2014.
I have photographed these award ceremonies since the mid-1990s. When I first got my studio lights (2008) I was reluctant to use them for these photos, thinking they might be overkill. Gradually I changed my mind, due to wanting to use better quality lighting and faster recycling than a 'speedlight' electronic flash. Thus I started using a two-umbrella setup by 2011.
Francesco has used this photo in multiple places, such as his biography page at INAF, (the Italian Istituto Nazionale di Astrofisica (National Institute for Astrophysics)), as well as what appears to be a newspaper site ( Cronache Maceratesi, ) plus his own personal blog's CV page.
