DESCRIPTION:Title: Mapping class groups\, coverings\, braids and groupoids.
 \n\nAbstract: Given a finite-sheeted\, possibly branched covering space be
 tween surfaces\, it’s natural to ask how the mapping class group of the co
 vering surface relates to the mapping class group of the base surface. In 
 this talk\, we will take a journey through this question for surfaces with
  boundary. It will feature appearances from the fundamental groupoid\, the
  Birman-Hilden theorem\, the Burau representation and new embeddings of th
 e braid group in mapping class groups.\n
