The PERPHOTO research project intends to explore the multiple interactions between photography and performing arts in theoretical, historical and cultural implications, as well as in Portuguese and international theatrical practice during the last 40 years, thus contributing to the definition of a new field of transdisciplinary research. Throughout the project, three distinct but interconnected lines of research are developed: Theory, Cartography, Practice.The project is part of the “Theatre and Image” research group of the Center for Theatre Studies of the School of Arts and Humanities of the University of Lisbon and is funded by the Fundação para a Ciência e Tecnologia (PTDC/ART-PER/31693/2017).
