I was awarded the 2016 Stefano Braccini PhD Thesis Prize by the Gravitational Wave International Committee (GWIC).  The prize announcement reads:

Dr. Gerosa received his Ph.D. from the University of Cambridge and was nominated by his adviser, Prof. Ulrich Sperhake. Dr. Gerosa’s thesis includes a wide variety of topics relevant to gravitational waves, as well as other topics in astrophysics: astrophysical explorations of accretion disks, analytically challenging work in mathematical relativity and post-Newtonian theory, and numerical relativity coding of supernova core-collapse in relativity and modified gravity.

The prize was officially awarded at the 12th Edoardo Amaldi Conference on Gravitational Waves. Here is a picture tweeted by Salvo :
