SUMMARY:Galaxy Transformations And The Quenching of Star Formation at 
 High Redshift\, Astronomy Colloquium\, Mauro Giavalisco\, University o
 f Massachusetts
DESCRIPTION:There is convincing evidence that massive galaxies (i.e. M
 ~M*) undergo profound structural and morphological transformations as 
 their star formation activity comes to a halt and they enter a phase o
 f passive evolution. We do not yet understand which physical mechanism
 \, or mechanisms\, among a number of plausible ones\, are responsible 
 for the quenching. Nor do we understand what drives the morphological 
 transformations. In this talk I will review some recent observations o
 f both structural and morphological transformations and of quenching i
 n galaxies at redshift 1<z<2.5\, namely at the peak of the cosmic star
  formation activity\, and discuss possible interpretations for the und
 erlying physics of both. I will also present very recent observations 
 that are informing us on the joint evolution of dark and baryon matter
  in galaxies and point to a possible common origin for both quenching 
 and structural transformations. I will conclude by discussing some of 
 the interpretations and by offering my speculations.
