DESCRIPTION:In this talk\, I will consider fermionic atoms confined to a q
 uasi-two-dimensional geometry. First\, I will expose the behaviour of the 
 pair correlations at high temperature by determining the spectral function
  and contact within the virial expansion. The calculated spectra are in qu
 alitative agreement with recent photoemission measurements\, thus suggesti
 ng that the observed pairing gap is a feature of the high-temperature gas 
 rather than being evidence of a pseudogap regime just above the superfluid
  transition temperature. I will further investigate the effect of the quas
 i-two-dimensional confinement and show that the higher confinement levels 
 can substantially modify fermion pairing.
