Abstract: It is now commonly accepted that most of the matter in the Universe is dark, but its identity is unknown. Weakly Interacting Massive Particles are well motivated candidates for dark matter. I will review the status of dark matter detection using direct, and collider searches. I then discuss two promising techniques for dark matter detection using radio observations: (i) Searching for excess synchrotron radiation from dwarf galaxies in the local group, and (ii) Observations of the highly redshifted 21cm line of neutral Hydrogen. I discuss recent results from the SCI-HI global 21cm experiment and future prospects.
