Search for Supersymmetry at CMS in lepton or photon final states

We present results of searches for Supersymmetry in signatures involving lepton or photon final states. These searches are performed with data collected by the CMS experiment at the LHC in pp-collisions at a center of mass energy of 7 TeV. Various data driven techniques used to measure the Standard Model background are demonstrated. The results are interpreted within the CMSSM as well as more general, simplified models
