Luca   Guardabassi DVM, PhD

Professor of Clinical Microbiology, Director of the One Health Center for Zoonoses and Tropical Veterinary Medicine

Dr. Luca Guardabassi is a clinical bacteriologist with a longstanding track record on antimicrobial resistance and veterinary antimicrobial therapy. Following graduation from the Faculty of Veterinary Medicine at Pisa University in 1994, he was awarded his PhD in Veterinary Microbiology at the Royal Veterinary and Agricultural University in Denmark in 2000. He became associate professor at the University of Copenhagen in 2004 and progressed to full professor in 2012. For 20 years he has conducted research on origin, evolution, population structure and epidemiology of resistant bacteria of clinical interest. His recent research focuses on identification of new antimicrobial helper drug targets and leads to revive older antibiotics towards which bacteria have developed resistance. This research activity continues at Ross University School of Veterinary Medicine, where he was appointed as Professor of Clinical Microbiology in November 2015.
