Prof Gilbert Greub is the current director of the Institute of Microbiology of the University Hospital of Lausanne (Switzerland). He is also Chef de Service and head of medical microbiology at the University Hospital of Lausanne. His activities mainly include research, teaching, & diagnostics as a microbiologist, as well as patient care as an infectious diseases specialist.

Born in 1967, he studied medicine at the University of Geneva. Then he did a MD degree at the University of Lausanne and a Phd at the University of Aix-Marseille (France). He specialized as FMH in internal medicine, FMH in infectious diseases, and FAMH in microbiology. Since 2004, he is leading the Center for Research on Intracellular Bacteria, a research center mainly dedicated to the study of chlamydia and chlamydia-related bacteria. Among others, his group recently succesfully studied the division of these bacteria (Jacquier et al Nature Comm 2014; Frandi et al Nature Comm 2014; Jacquier et al Biol Chem 2015), identifying possible new future drug targets, as well as chlamydial toxins (Ardissone & Greub, Appl Environ Microbiol 2024). For all this research on chlamydiae, G Greub received several prices including the European ESCMID young investigator award (2006), the Viollier award (2010), the Leenaards award (2011), the Naef Price (2010), and the Fond Carlo - Philanthropia price from the Lombard-Odier foundation (2016). He is also past president of SSM 2016-2018, the current chair person of the ESCMID study group on mycoplasma and chlamydia (ESGMAC) and the chairman of the International sucommittee for chlamydial taxonomy. Since January 2022, he is leading the national center for tick-borne infections, being active both on bacteria from ticks such as Rhabdochlamydia, Rickettsia, Anaplasma, Borrelia and virus from ticks such as tick-borne encephalitis virus and alongshanvirus. Recently he funded JeuPRO, a company that is distributing the games Krobs & MyKrobs, two games that he created and edited with C. Kebbi from the Institute of Microbiology. In 2026, he also published a comic book on resistant microbes and co-authored an article in Science of the paleomicrobiology of Treponema.
