Characterizing Blue Straggler Star Populations in Globular Clusters
  using HST Photometric Survey Data
  We present early results from a detailed analysis of the BSS population in
Galactic GCs based on HST data.Using proper motion cleaning of the
color-magnitude diagrams we construct a large catalog of BSSs and study some
population properties.Stellar evolutionary models are used to find stellar mass
and age estimates for the BSS populations in order to establish constraints
related to the dynamical interactions in which they may have formed.
