A matter of life and death: the formation and destruction of planetary bodies
… around both of these questions, by studying accretion processes across the lifetime of planetary bodies. My thesis is organized chronologically, starting with the birth of planetary building blocks, and ending with the destruction of fully-formed planets. Besides the shared topic of planetary …

A Global Hydrodynamic Investigation into the Transport of Material in Protoplanetary Discs
… in planet formation theory have highlighted pebble accretion as a crucial process, offering a solution to the meter-sized barrier in dust growth and significantly reducing timescales in core accretion models. This efficient growth mechanism enables the formation of massive planets within disc …

Planet formation, resonant drag instabilities, and vortices
… the metre-scale barrier, planetesimal accretion, pebble accretion, cooling-limited gas accretion, and runaway gas accretion. Finally, I present six possible bridges over the metre gap: sturdy grains, pressure bumps, the gravitational instability, the Safronov-Goldreich-Ward mechanism, …
