DESCRIPTION:As planets form and grow within gaseous protoplane
 tary disks\, the mutual gravitational interaction 
 between the disk and planet leads to the exchange 
 of angular momentum\, and migration of the planet.
  I review the current understanding of disk-planet
  interactions\, focussing in particular on physica
 l processes that determine the speed and direction
  of migration. The role of Lindblad and corotation
  torques as a function of the disk properties will
  be discussed\, as well as the evolution of eccent
 ricities and inclinations. Finally\, I address the
  question of how well global models of planetary f
 ormation that include migration are able to match 
 observations of extrasolar planets.
