Roser is a finishing Ph.D. student in the Spanish, Portuguese, and Latin American Studies department. Her research focuses on the representation of Judaism in 17th-century Spanish theatre. The ideological uses of Jewish figures in Spain find its roots in the Middle Ages. During this epoch, fear of otherness led to the creation of stereotypes that deeply codified political and social language in the following centuries.

As the administrator of the Centre for Late Antique and Medieval Studies (CLAMS), Roser helps organise the events planned for the academic year, curates the social media accounts, and manages other social events such as a Film Club in collaboration with other research centres.
