I gained a PhD in Medical Microbiology from the University of Leeds and became interested in tuberculosis (TB) in 1999 during my first postdoctoral position at University College London. In 2002 I moved to the Jenner Institute at the University of Oxford as an immunologist for the first-in-man trial of a new TB vaccine, MVA85A. After 10 years at the Jenner Institute I moved to the London School of Hygiene & Tropical Medicine to establish my group, based in the Immunology and Infection Department, which focuses on immune correlates and the host response to TB vaccination. In 2015 I became Director of the TB Centre: http://tb.lshtm.ac.uk/ at the London School of Hygiene & Tropical Medicine and in 2016 I became co-chair of the T-cell Immunology working group for the Collaboration for TB Vaccine Discovery (CTVD) at the Bill & Melinda Gates Foundation.
