Marios completed his BSc in Biomedical Sciences at Imperial College in London, working with Professor Wendy Barclay on the molecular virology of influenza B viruses. He then obtained a Masters degree in Systems and Synthetic biology, also at Imperial College. Marios subsequently undertook a PhD with Professor Katherine Kedzierska within the Department of Microbiology and Immunology, University of Melbourne, focusing on understanding protective immunity to influenza viruses, especially the understudied but clinically relevant influenza B viruses. He is now a Senior Research Fellow with the Kent Group at the Doherty Institute, working on dissecting the antigenic evolution and antibody responses to influenza B viruses in order to rationally designing a universal influenza B virus vaccine. He is interested in exploring the possibility of influenza B virus eradication.
