**Abstract.**

Artinian Gorenstein algebras is one of the main objects in studying the Lefschetz properties in many branches of mathematics. The Jordan type of an Artinian algebra A and a linear form L determines the Jordan blocks of the multiplication map by L on A. Jordan type is a finer invariant than the weak or strong Lefschetz property. In this talk, I will summarize some of the results and open problems on Jordan types of graded Artinian Gorenstein algebras that are mainly of low codimensions.
