Professor Pierre Miossec MD PhD is a distinguished professor of Clinical Immunology at the University of Lyon, France. He trained with Morris Ziff as a research fellow at the University of Texas in Dallas, where he started his research on the role of cytokines and T cells in arthritis. He was the first to identify the destructive properties of interleukin-17 and to introduce the concept of its production by a new T cell subset. This has led to the targeting of IL-17 in a growing number of diseases. He was awarded the EULAR Robecchi Prize for Rheumatology Research in 1995 and the most prestigious Carol Nachman prize in 2010 for this contribution. He gave the Morris Ziff lecture in Dallas in 2010. He received the distinguished basic investigator award from the American College of Rheumatology in 2015, and the Gerald Weissmann prize from New York University in 2016. He was elected senior member of the Institut Universitaire de France in 2011, membre correspondant de l’Académie Nationale de Médecine in 2016, member of the prestigious Association of American Physicians in 2019, Master of the American College of Rheumatology in 2020 and membre titulaire de l’Académie Nationale de Médecine in 2021.
