In this thesis we investigate the neutrino portal dark matter which tries to explain non-baryonic dark matter and the neutrino masses at the same time. Bearing in mind that natural theories like the Minimal Supersymmetric Standard Model also provide a WIMP type candidate for dark matter, we also calculate the sensitivities of the High Luminosity (HL) and High Energy (HE) upgrades of the Large Hadron Collider to strong supersymmetry signals. Firstly, we study the feasibility of the indirect detection of dark matter in a simple model using the neutrino portal. We derive the existing constraints on this scenario from Planck cosmic microwave background measurements, Fermi dwarf spheroidal galaxies and Galactic Center gamma-rays observations, and AMS-02 antiprotons observations. Secondly, by modifying our simple model, we analyze the scenario in which a thermal dark matter annihilating to standard model neutrinos via the neutrino portal. We derive existing constraints and future projections from direct detection experiments, colliders, rare meson and tau decays, electroweak precision tests, and small scale structure observations. Finally, we evaluate the sensitivities of the High Luminosity (HL) and High Energy (HE) upgrades of the LHC to gluinos and stops, decaying through the simplified topologies. Our HL-LHC analyses improve on existing experimental projections by optimizing the acceptance of kinematic variables.
