Professor Serge Mostowy is a Lister Institute of Preventive Medicine, Wellcome Beit and Wellcome Trust Senior Research Fellow. He studied physics (B.Sc.), evolution (M.Sc.), and microbiology and immunology (Ph.D.) at McGill University, Canada. After postdoctoral work on the cell biology of infection at Institut Pasteur in France, he moved to Imperial College London in 2012 to start a Wellcome Trust Research Career Development Fellowship. In 2018 Serge was appointed professor of cellular microbiology at the London School of Hygiene & Tropical Medicine, where his lab investigates novel roles for the cytoskeleton in innate immunity. The Mostowy lab has also developed the zebrafish as an important model to study the cell biology of infection and the therapeutic potential of targeting the cytoskeleton in vivo.
