The ubiquity and diversity of the exoplanet population suggests that planet formation is an efficient process. However, the theoretical road from dust to planets is all but rocky. Dust grains immersed in a gaseous protoplanetary disk face several challenges in growing into planetesimals and beyond. I will present recent work on dust-gas interaction in protoplanetary disks, including the effect of hydrodynamic turbulence on dust settling and the streaming instability for planetesimal formation. I will also discuss how newly formed planets interact with 2D and 3D dusty disks. Finally, I will showcase a new effort in combining hydrodynamic simulations with artificial intelligence to find hidden planets in observed protoplanetary disks.
