He teaches at Queen Mary University of London, where his research focuses on global health and the social determinants of disease. His debut book, *Pathogenesis: A History of the World in Eight Plagues* (2023), explores how infectious diseases have shaped human civilization, from the fall of Rome to colonialism and industrialization.
