"The rich diversity of exoplanets discovered in various physical environments clearly\r\nshows that planet formation is an efficient process with multiple outcomes. To un-\r\nderstand the emergence of newborn planets, one can rewind the clock of planetary\r\nsystems by investigating the formation and evolution of their natal environment,\r\nthe so-called protoplanetary disks. In the core accretion scenario, rocky planets\r\nsuch as the Earth are thought to be formed from cosmic dust particles that grow\r\ninto pebbles and planetesimals, the building blocks of planets, later assembling to-\r\ngether. An intricate puzzle in this theory is how exactly these building blocks are\r\nformed and kept long enough in the natal protoplanetary disk.\r\nProtoplanetary disks are weakly magnetized accretion disks that are subject to\r\nthe magnetorotational instability (MRI). It is to date one of the main candidates\r\nfor explaining their turbulence and angular momentum transport. The nonideal\r\nmagnetohydrodynamic effects prevent the MRI from operating everywhere in the\r\nprotoplanetary disk, leading to MRI active regions with high turbulence and non-\r\nMRI regions with low turbulence. It has been hypothesized that these variations\r\nin the disk turbulence can lead to pressure maxima where dust particles can be\r\ntrapped. In these so-called dust traps, dust particles can grow efficiently into peb-\r\nbles and potentially planetesimals. Yet, it is still an open question how this MRI-\r\npowered mechanism shapes the secular evolution of protoplanetary disks, and how\r\nit is involved in the first steps of planet formation. It is because the interplay of gas\r\nevolution, dust evolution (dynamics and grain growth processes combined) and\r\nMRI-driven turbulence over millions of years has never been investigated.\r\nThe central goal of this thesis is to bridge the gap in the core accretion scenario\r\nof planet formation by building the very first unified disk evolution framework\r\nthat captures self-consistently this interplay. The unique approach adopted in this\r\nthesis leads to an exciting new pathway for the generation of spontaneous dust\r\ntraps everywhere in the protoplanetary disk, which can be potential birth-sites for\r\nplanets by forming and keeping their necessary building blocks."^^ .
