My research interests span a wide range of topics in cosmic structure formation and evolution, at both large and small scales. The formation and evolution of galaxies, the origin, growth, pairing and coalescence process of supermassive black holes, and the formation of protoplanetary disks and massive planets (gas giants and Super-Earths) are among the main target areas. The common denominator of these diverse problems is the underlying physics, predominantly radiation hydrodynamics married
