PRESENTATION Born in Viterbo, December 10th 1967. He got his master degree in 1994 and his PhD degree in Biological and Biochemical Evolution in 1999 at the University of Viterbo “Tuscia”. During his training he has worked as a Visiting Fellow at the National Institute on Aging-NIH at the Johns Hopkins University, Baltimore (USA), under the supervision of Dr. Vilhelm Bhor, where he started out some studies on the understanding of mechanisms of DNA repair and transcription, and the consequences of these defects in the patients. In 2002 he joined the group of Dr. Egly, in Strasbourg, a pioneeristic laboratory in the transcription field. Here, he has published a number of milestone papers that lead to a better understanding of the molecular basis of human syndromes such as xeroderma pigmentosum, trichothiodystrophy and Cockayne syndrome. Of note, he contributed to provide new insights into the understanding of the molecular basis associated to the action of CSB gene in either RNA polymerase I and RNA polymerase II basal and activated transcription (Bradsher et al., 2002; Proietti De Santis et al., 2006). Although these years in France have been successful and scientifically stimulating, encouraged by Prof. Egly, he decided to return to Italy to establish his own research group. Therefore, he applied for the governmental program “Brain Gain” (Rientro dei Cervelli), which sponsors reintegration of young scientists, after a prolonged period abroad, into the Italian research infrastructures. Eventually, he has obtained a contract which supports his salary for 3+1 years and in 2005 he has came back to Italy with the aim to start an independent unit at the University of Viterbo, where, a few years before, he spent part of his PhD program. There, He has continued his studies on Cockayne syndrome with the aim to deeply investigate the molecular mechanisms responsible of this disease. He has been awarded with several fellowships (EMBO, Poste Vert INSERM, FRM (Fondation de Recherche Medicale). At present, he is Associate Professor of Genetics of Aging and Longevity and Human genetic diseases courses at the Department of Ecology and Biology Sciences of the University of Viterbo – Italy. He is coordinating or has coordinated projects sponsored by Associazione Italiana per la Ricerca sul cancro (AIRC), Ministero per lo Sviluppo Economico (MISE), Telethon, and Fondazione per l’Avanzamento della Medicina Molecolare (FARMM). He is referee for several international journals. Expert of European Commission - 2009 and 2014. Research Area Main scientific interest is focussed on investigating the molecular mechanisms involved in DNA repair, transcription and genomic instability. In particular focus is placed on the study of three human diseases which are Xeroderma pigmentosum, Trichothiodistrophy and Cockayne syndrome and more generally on the role of DNA repair and transcription systems on aging and carcinogenesis.
