Dr Malick Gibani

Malick Gibani is a Consultant in Infectious Diseases at Chelsea and Westminster Hospital and a Clinical Associate Professor in Bacterial Vaccinology at Imperial College London. He completed his medical training at the University of Oxford before continuing his clinical training in London, where he subsequently joined the Oxford Vaccine Group in the Department of Paediatrics. There he undertook a DPhil focusing on Salmonella Typhi and Paratyphi A human challenge models.

Since 2019, he has worked in the Department of Infectious Diseases at Imperial College London, combining active NHS clinical practice with a research programme centred on bacterial vaccines for AMR and pandemic preparedness. His laboratory works across a range of pathogens, including Salmonella, Klebsiella, Yersinia and Staphylococcus aureus, with a particular focus on controlled human infection models as platforms to accelerate vaccine development and characterise host-pathogen interactions.

He is the PI on the Challenge Against Non-Typhoidal Salmonella (CHANTS) and Protection Against Invasive Non-Typhoidal Salmonella projects (PAiNTS). CHANTS established the first-in-human Salmonella Typhimurium challenge model and is defining immune correlates of protection. More recently, his work has expanded to apply controlled human infection models to a broader range of research questions, including the role of the gut microbiome in colonisation and host resistance to Salmonella infection.
