SUMMARY:Observational Assessment of Stellar Feedback in Star-Forming R
 egions\, Astronomy Colloquium\, Laura Lopez\, Ohio State University
DESCRIPTION:Stellar feedback has a profound influence in many astrophy
 sical phenomena\, yet it is often cited as one of the biggest uncertai
 nties in star and galaxy formation models today. This uncertainty stem
 s from a dearth of observational constraints as well as the great dyna
 mic range between the small scales (<1 pc) over which feedback occurs 
 and the large scales (>1<br>kpc) on which galaxies are shaped by that 
 feedback. In this talk\, I will show how multiwavelength observations 
 can be used to overcome these challenges to assess the role of many st
 ellar feedback mechanisms\, including radiation\, stellar winds\, supe
 rnovae\, and cosmic rays. I will present results from the application 
 of these approaches to a variety of sources and discuss the implicatio
 ns regarding the dynamics of star-forming regions and the launching of
  galactic winds. Finally\, I will highlight the exciting prospects of 
 using current and upcoming facilities to explore feedback in diverse c
 onditions.
