DESCRIPTION:The abundance of close-in super-earth/sub-neptunes is one of t
 he big surprises from the Kepler mission. Most stars appear to host one of
  these planets yet they were completely missing from our ideas of how plan
 et formed a decade ago. The fact that many of these planets have large vol
 atile H/He atmospheres at small separations indicates that hydrodynamic es
 cape of these atmospheres cannot be ignored. Combining recent observationa
 l advances from the California-Kepler Survey\, with a theoretical understa
 nding of how exoplanetary atmospheres evolve I will provide clues as to ho
 w close-in\, small planets formed. This will include inferences gleaned fr
 om the "evaporation-valley" and how the properties of these planets vary w
 ith host star metallicity.
