To do this I combine analytical perturbative tools with numerical nonlinear simulations in which I solve the Einstein equations together with those of relativistic hydrodynamics or magnetohydrodynamics. I do this in the endless process of comparing theoretical results and predictions with astronomical observations.

Previously an Associate Professor and Director of the Computing Centre at SISSA (Italy), I now lead a group of scientists and students at the Albert Einstein Institute working on the modelling of sources of gravitational waves. A lot more on our science and the results of the numerical-relativity group can be found here.
