Planet formation with ALMA & JWST: Chemical signatures of pebble migration in protoplanetary discs

The properties of planetary systems depend sensitively on the physical and chemical structure of the protoplanetary discs in which they form. At the same time, the processes associated with planet formation can dramatically influence the evolution of protoplanetary discs. In this talk, I will focus on the ways in which planet formation via core accretion can shape the chemical environment of growing protoplanets. In particular, I will discuss the consequences of dust coagulation, pebble drift, planetesimal formation and pebble accretion on gas-phase molecular and elemental abundances, highlighting exciting ongoing efforts to study the signatures of these processes with ALMA and JWST.
