Over his career, John Bally has made lasting contributions to many aspects of stellar feedback and the ecology of galaxies. On the event of his retirement, we come together to review the field and chart the future through a wide-ranging conference on the topic of star formation, stellar feedback, and galactic ecology.

The focus of this conference will be understanding the role of star formation and stellar feedback in driving galactic evolution; The conference aims at identifying a number of key steps in the feedback ladder and using studies of nearby galactic sources dominated by feedback to quantitatively understand the role of feedback in shaping the local universe around us.

The meeting will focus on:

• Stellar feedback on molecular cloud scales
• Stellar feedback and galactic ecology
• Stellar feedback in extreme environments
• Stellar feedback galactic scales

By developing a “feedback ladder” from the scale of individual O stars, to small clusters, to super star clusters, to galactic outflows, we expect to quantitatively address the role of stellar feedback in the ecology of galaxies and how feedback by massive stars depend on the properties of the environment.
