SUMMARY:From Cores to Disks: Probing the Initial Conditions for Stars 
 and Planets\, Astronomy Colloquium\, Sarah Sadavoy\, Harvard CfA
DESCRIPTION:Star formation is a multi-scale problem and there are nume
 rous observational and theoretical challenges to connect large molecul
 ar clouds that span several parsecs to the planet-forming disks around
  young stars with sizes of ~ 100 au.   I bridge the astrophysical proc
 esses seen across these widely different scales using observations of 
 interstellar dust and gas. This presentation focuses on my recent obse
 rvations of cloud structure from the Herschel Space Observatory and du
 st polarization with the ALMA interferometer.  In particular\, my ALMA
  observations represent the first unbiased survey of dust polarization
  in young protostellar disks and probe both magnetic fields and dust g
 rain growth at early protostar stages.  I also describe my future goal
 s using new and existing facilities to answer fundamental questions ab
 out the formation of both stars and planets.
