My main work deals with electromagnetic and gravitational-wave transients, as well as stellar and planetary dynamics. I study the origins of thermonuclear supernovae explosions through hydrodynamical simulations as well as analysis of observational data. On the dynamics side, I explore the evolution of multiple systems (triple stellar systems, and multi-planet systems) through dynamical and secular interactions and their coupling to stellar evolutionary processes.  I  also study the collisional dynamics of stars in dense systems such as globular clusters and clusters around massive black holes and the strong interactions of stars with black holes, including tidal disruption of stars, gravitational wave sources, the capture of stars close to the massive black hole in the Galactic center and ejection of hypervelocity stars. Finally, I also study planet formation and try to understand the origin and evolution of the Solar system and of exoplanet systems, including the origin of moons (Earth-Moon and gas-giant moons).
