Results will be presented from searches looking for a large transverse momentum imbalance motivated by dark matter and supersymmetry, using a sample of proton-proton collisions collected at a center-of-mass energy of 13 TeV in 2015 with the CMS detector at the LHC. An inclusive analysis for hadronic jets and missing transverse momentum (MET), measured using the MT2 variable, will be covered, as well as an analysis searching for a pair of leptons with opposite-sign and the same flavor, hadronic jets, and MET. The latter analysis looks for one of two features in the mass spectrum of the lepton pair: either a resonance compatible with the Z boson mass or a kinematic edge. The results of each search are interpreted in simplified models of supersymmetry.
