DESCRIPTION:There is strong evidence from cosmological observations that t
 he dominant form of matter in the universe is dark matter. However\, littl
 e is known about its nature. Recent reports of a possible dark matter sign
 al from several direct detection experiments have further highlighted the 
 need for independent verification from non-astrophysical experiments\, suc
 h as colliders.\nI will present the results of  a search for dark matter p
 erformed using data collected by the CMS experiment at the LHC in proton p
 roton collisions at a center-of-mass energy of 7 TeV.  The search is perfo
 rmed using a monojet plus missing transverse energy signature. The results
  are interpreted within the framework of an effective field theory and use
 d to place bounds on the dark matter-nucleon scattering cross-section whic
 h can be directly compared with those from the direct detection experiment
