This dissertation investigates the flavor mixing effects in Supersymmetric models on electroweak precision observables, Higgs boson mass predictions, B-physics observables, quark flavor violating Higgs decays and lepton flavor violating charged lepton decays and lepton flavor violating Higgs decays. We have studied the flavor mixing effects in model independent way. We also studied effects of flavor mixing of squarks in CMSSM and of sleptons in CMSSM with seesaw extension. For the model independent study, we were able to put new constraints on the flavor violating deltas from electroweak precision observables in the case of squarks whereas no new constraints could be set for the case of slepton deltas. In our analysis of minimal flavor violating CMSSM, we found that flavor mixing can have large impact to electroweak precision observables, enabling us to put new constraints on parameter space in CMSSM. However flavor mixing effects to Higgs boson masses and B-Physics observables were found to be negligible.
