Claudia Fiorillo graduated in biological sciences in 1992. In 1996, she attained the school of specialization in biochemistry and clinical biochemistry. In March 2000, she earned a Ph.D. In September 2000, she was appointed university researcher in clinical biochemistry (BIO12) at the University of Florence Faculty of Medicine. Since 2003, she has been a confirmed university researcher. She is actively involved in the study of the molecular pathways evoked by oxidative stress in several disorders, in particular, dermatologic diseases (vitiligo and psoriasis). Moreover, she is interested in the study of the molecular basis of the toxicity of protein aggregates in various cell types. The post-translational modifications responsible for alterations in fibrinogen function represent another important and recent topic of interest. She participated in several research programs, in particular, the Projects of Relevant National Interest "Insufficienza cardiac (heart failure)", "Molecular and metabolic myocardial damages induced by post-ischemic reperfusion and mechanisms of protection" and "Mechanisms of injury and protection in the ischemic myocardium". She is a member of the Società Italiana di Biochimica clinica e Biologia molecolare clinica (SIBioC), the Società Italiana di Biochimica (SIB), and of the Società Italiana per lo studio dell\emostasi e della trombosi (SISET).
