Lorenzo Petrachi is a doctoral student in Transcultural Humanistic Studies (cycle XXXVIII). His research project centers on the genealogy and politics of friendship in the modern age, exploring its connection to the works of Michel Foucault, methodologies derived from the history of emotions, and the forms of dissent within French revolutionary feminist and homosexual groups of the 1970s. He specializes in philosophy of history and critical theories of subjectivation, emphasizing the history of emotions and systems of thought, queer theory, and the reception of Nietzschean thought in twentieth-century French philosophy. As a co-founder of the Dalla Ridda project at the University of Bologna and a member of the editorial board of the journal “materiali foucaultiani”, he has contributed to the editing and translation of several Italian editions of Michel Foucault’s works. In 2022, he authored a monograph titled Rovine dell’amicizia: Il progetto incompiuto di Michel Foucault, published by Orthotes.
