With the first-year data release from the Fermi Gamma-ray Space Telescope last summer, the community was given its best chance to finally observe for the first time the diffuse high-energy emission from normal (non-AGN), star forming galaxies. In particular, Fermi is sensitive to photon energies ( 1 GeV) that will allow us to constrain the hadronic contribution to gamma-ray and cosmic ray production in starburst galaxies. Unlike the extreme targets typically observed at these energies (AGN), starbursts are normal galaxies whose diffuse gamma-ray emission should nevertheless be strong because of their many supernovae and consequent high cosmic ray densities. We present the results of a search for gamma-ray emission from nearby star forming galaxies using the Fermi first-year data. Along with this work, we present new models of the expected gamma-ray emission from these sources.
