Thousands of exoplanets have already been discovered. None of them is, however, the same in properties as our Solar System. How diverse are planets and planetary systems in the Galaxy? Is our Earth an ordinary or very unique planet? My research attempts to decipher the origin, structure, and diversity of planets and planetary systems through theoretical modelling and observation.
