SUMMARY:Modeling the Chemical and Dynamic Feedback Mechanisms of Plane
 t Formation\, Astronomy Colloquium\, Eric van Clepper\, WiCOR
DESCRIPTION:Planets form in protoplanetary disks\, inheriting the comp
 osition of the solids and gas present at their formation location. The
 se PPDs\, however\, are constantly evolving\, with dust growth\, fragm
 entation\, and pebble drift driving chemical evolution in the gas.  Wh
 ile these effects are beginning to be understood\, what is less well c
 onstrained is the feedback mechanisms between growing planets and the 
 disks in which they form. In this talk\, I will discuss recent work us
 ing a variety of computational techniques to create a wholistic\, self
 -consistent model of planet-disk interactions and the resulting disk c
 hemical evolution.  By combining constraints from disk observations\, 
 meteorite measurements\, and exoplanet atmospheres I argue for an acti
 ve stirring of dust near the orbit of giant planets\, vertically mixin
 g small dust grains and driving grain surface chemistry. This stirring
  may have important implications for the formation and transport of co
 mplex organic molecules throughout the disk\, including delivery to in
 ner terrestrial planets.
