Sidonia Făgărășan

Sidonia Făgărășan is a Romanian biological scientist who is a professor at the Riken Institute in Japan. Her research considers the molecular mechanisms that underpin processes in gut microbioata and the mucosal barrier. In 2020, she was awarded the Kobayashi Foundation Award.

Early life and career Făgărășan completed training in clinical medicine at Iuliu Hațieganu University of Medicine and Pharmacy. She was a medical resident in Cluj-Napoca, where she completed various training positions and was eventually made assistant professor. During her early career she became interested in the molecular mechanisms that underpin immune homeostasis. In 1998 she moved to Japan as a Visiting Researcher at Kyoto University, and remained there to complete a doctorate.

Research Făgărășan contributed to the discovery of Activated Induced Deaminase, and went on to short the role of AID in gut homeostasis. In 2002, Făgărășan was appointed leader of the Riken Laboratory for Mucosal Immunity at the Research Centre for Allergy and Immunology.

Făgărășan looks to understand the mechanisms between the microbiota and the immune system at the mucosal barrier. She looks to understand how the gut immune system contributes to the diversity, balance and metabolic functions of microbes. She showed that T-cells, the immune systems that protect the body from infections, change the body's metabolism.
