His doctoral thesis at the Faculty of Fine Arts, University of Basra examined the semantic pattern and its works in the performance of the Iraqi theater actor-selected examples
The thesis presented by researcher Rana Faleh Lafta aims to identify the work of the semantic pattern in the performance of the Iraqi actor.
The thesis included the topic of representational performance, which depends on the semantic expression formats through its aesthetic and intellectual elements, which produces a visual speech of multiple semantic formats. 
The thesis concluded that the theater, through past stages, began to recognize multiple rituals in which the performance of the theatrical actor expresses his tools through expressive-semantic formats to produce an open visual speech.
