The identity of dark matter remains one of the biggest mysteries in science today. Weakly Interacting Massive Particles or WIMPs are one of the leading candidates for the dark matter of the Universe. If the dark matter particles have weak interactions, they annihilate at early times, releasing energy. The speaker shall discuss three cosmological probes of WIMP dark matter: (i) The cosmic microwave background, (ii) Deep radio observations of dwarf galaxies, and (iii) Global Hydrogen 21 cm observations. He will discuss current bounds on dark matter properties, and how experiments in the near future can improve these constraints
