DESCRIPTION:The large variety of observed planetary systems is rooted in t
 he complex physical and chemical processes that lead to their formation. S
 patially and spectrally resolved observations of molecular lines of planet
  nurseries - protoplanetary disks - can be leveraged to characterise simul
 taneously the dynamical state of the planet formation environments\, and t
 heir chemical inventory. In this talk\, I will show a new exquisite charac
 terisation of disk kinematics by the exoALMA Large Program\, a large effor
 t that has involved more than 50 scientists for the last three years. Thes
 e observations provide a novel methodology to determine the physical struc
 ture of disks\, constrain their masses\, reveal physical mechanisms yieldi
 ng annular dust concentrations\, and potentially unveil embedded planets. 
 In jointure with direct imaging searches of such planets\, and a chemical 
 inventory of disk gas abundances\, these observations yield the most accur
 ate characterisation of protoplanetary disks to date. I will end the talk 
 by discussing the future of this exciting research field\, and potential n
 ew efforts to extend these studies to a much larger and more representativ
 e sample of disks.\n\n
