It has been conjectured that every smooth projective variety carries an Ulrich bundle. The answer to this is not known in general but is known in the case of certain projective varieties. In this talk, I will give an introduction to Ulrich bundles. I will also discuss the existence of Ulrich line bundles over double covers of the projective plane. This is based on joint work with A.J. Parameswaran.
