DESCRIPTION:We are in the golden age for the search for high-redshift gala
 xies\, made possible by state of the art instruments including the Hubble\
 , Subaru and Keck Telescopes.  Two such classes of galaxies\, namely Lyman
  Alpha Emitters (LAEs) and Lyman Break Galaxies (LBGs) have rapidly been g
 aining popularity as theoretical probes of the epoch of reionization\, gal
 axy evolution and the dust enrichment of galaxies in the first billion yea
 rs.  In this talk\, I will present a broad overview of the semi-analytic a
 nd numerical galaxy formation models proposed to explain the observed data
  sets.  I will also discuss the results from these models regarding reioni
 zation\, the physical nature of these galaxies and the LAE-LBG connection.
   Finally\, I will also show how these galaxies can be used to study the e
 volution of the Fundamental Metallicity Relation linking the stellar mass\
 , star formation rate and gas metallicity\, from z=0 to these high-redshif
 ts.\n
