Professor Guardiola received her Ph.D. from the University of Pennsylvania, and her degree of "Licenciada en Filología Hispánica" from the Universitat Autónoma de Barcelona. She specializes in nineteenth and twentieth century Spanish literature, with an emphasis in women writers. She has written on romantic authors such as Cecilia Böhl de Faber, Gertrudis Gómez de Avellaneda and Antonio García Gutiérrez. She also works on the literary production of "fin de siglo" writers such as Emilia Pardo Bazán, and Benito Pérez Galdós. She has done research on Catalan women writers of the early twentieth century, Caterina Albert and Mercé Rodoreda, creators of a modernist style of their own. She has done extensive work
on important writers of the second half of the twentieth century: Carmen Martín Gaite, Carme Riera, Montserrat Roig and many others. She has presented at many national and international literary conferences. She is presently writing a book chapter on two novels by Carmen Martín Gaite for the prestigious Modern Language Association "Approaches to Teaching" series.
She published La temática de García Gutiérrez (La mujer), a book on the female characters and their role in the works of Antonio García Gutiérrez, a Spanish playwright whose literary production spans the nineteenth century (PPU, 1993). Professor Guardiola prepared a critical edition of García Gutiérrez's El trovador (Crítica, 2006), the play that Verdi used for the libretto of his renowned opera "Il trovatore". This critical edition is the first one to include the author's signed 1836 manuscript and is included in the emblematic Biblioteca Clásica collection directed by Francisco Rico. The edition of Pepita Jiménez, an important realist novel, is designed to help the student understand the essential aspects of late nineteenth century narrative style (Punto de Lectura, 2001).
Professor Guardiola has extensive experience directing study abroad programs. She directed the Hamilton College and St. Lawrence University programs in Madrid, Spain, several times. Under her directorship the programs have been updated to enhance the cultural experience of the participants.
At Swarthmore, Professor Guardiola teaches courses that focus on the representation of the Spanish Civil War in literature and cinema, nineteenth and twentieth century women writers, a survey on Spanish literary history, and the role of memory in literary, film and cultural narratives to build national identity. Additionally, she offers two seminars, one on Federico García Lorca and another in 19th-century Spanish literature, entitled "Héroes y villanos: el siglo XIX español y la democratización literaria."
