Changing paradigms in planet formation

In the last years, we discovered many exoplanet systems with architectures that significantly deviate from the Solar System. At the same time, unprecedented progress has been made in observations of the birthplaces of planets, the disks surrounding young stars. These developments have challenged the classical theory of planet formation. In this talk, I will discuss my work on dust evolution in the circumstellar disk and the formation of planetary building blocks and present the emerging new theory of planet formation.
