I am currently Research Director and I am working at the HEAG in Rome since 1997.
I had several (scientific) travel mates during all these years. I have started (and still working on) with the development of timing techniques to search for coherent signals in X-ray sources and their application to the astronomical archives of X-ray missions (CATS@BAT and EXTraS recent projects). I am involved in Magnetar (the strongest magnets in the Universe) studies since 1993 when I first discovered pulsations in one of the source prototype 4U0142+614. I have been involved since 1999 in the study of an extreme X-ray binary hosting two white dwarfs when I discovered the shortest orbital period currently known (HM Cnc; Porb=5.4minutes). More recently, I am focusing onto Ultraluminous X-ray Sources hosting neutron stars accreting at super-Eddington rates (with the discovery of the most distant and luminous X-ray pulsars in NGC5907). Other topics of interest are GWs, GRBs, FRBs, search of the optical counterpart of new X-ray pulsators, time domain astronomy. I am teaching at “Tor Vergata” University since many years (“High Energy Astrophysics” course).
