Indirect Searches for Dark Matter with the Fermi Large Area Telescope

There is overwhelming evidence that non-baryonic dark
matter constitutes ~23% of the energy density of the universe.  Weakly Interacting Massive Particles (WIMPs)
are promising dark matter candidates that may produce gamma rays via
annihilation or decay detectable by the Fermi Large Area Telescope (Fermi
LAT).  A detection of WIMPs would also
indicate the existence of physics beyond the Standard Model.  I will present recent results from indirect
WIMP searches by the Fermi LAT Collaboration. 
I will focus on our recent search for gamma-ray spectral lines from WIMP
annihilations with 4 years of data. 
There has been recent excitement with the report of a line-like feature
localized in the galactic center around 130 GeV.  I will be discussing what our search finds
and the systematic checks we've performed on potential signals.
