"Migration of Low-mass Planets in Dusty Protoplanetary Disks"  
  
Fast inward migration of planetary cores embedded in gaseous  
disks is a common problem in the current planet formation paradigm. Even  
though dust is ubiquitous in protoplanetary disks, its dynamical role in  
the migration history of planetary embryos has not been considered until  
recently. In this talk, I will show that the scattered pebble-flow  
induced by a low-mass planetary embryo leads to an asymmetric  
dust-density distribution that is able to exert a net torque. Building  
on the results or a large suite of numerical simulations for measuring  
this dust torque under a wide range of conditions, I will present the  
first study showing that dust torques can have a significant impact on  
the migration and formation history of planetary embryos
