SUMMARY:Examining Galaxy Formation and Evolution with the Milky Way an
 d Its Satellites\, Astronomy Colloquium\, David Nidever\, University o
 f MI
DESCRIPTION:How galaxies form and evolve remains one of the cornerston
 e questions in our understanding of the universe on grand scales.  The
  Milky Way and its satellites are a local laboratory for studying the 
 evolution and properties of galaxies of various masses in great detail
 .  I will highlight some recent results from three projects that are p
 roviding new insights into the structure and formation history of the 
 Magellanic Clouds and the Milky Way.  First\, an extensive study of th
 e stellar periphery of the Magellanic Clouds reveals that they are muc
 h more extended than previously thought which has implications for str
 ucture formation on small scales.  Second\, I have undertaken a large-
 scale survey to map out the gaseous Magellanic Stream.  These observat
 ions provide important constraints on the orbits and<br>
\ninteraction
  history of the Magellanic Clouds with each other and the Milky Way.  
 Finally\, I will discuss SDSS-III/APOGEE\, a near-infrared\, high-reso
 lution spectroscopic survey of ~100\,000 stars in the Milky Way.  With
  only the first year of data\, APOGEE has already produced a number of
  important results especially in the Galactic bulge\, with many more t
 o come.
