Dr Sam Willcocks

After completing my PhD in innate immunology at the Royal Veterinary College, I joined LSHTM in 2008 for my first post-doc position. Working with Prof Ulrich Schaible, I investigated host-pathogen interactions in tuberculosis infection, particularly the role of cell-wall lipids and antimicrobial peptides. I have since worked with Prof Brendan Wren and Dr Richard Stabler, using modern molecular techniques to identify virulence factors in pathogens including Yersinia pseudotuberculosis, Burkholderia pseudomallei and Acinetobacter baumannii. In 2017, I was awarded an MRC Confidence in Concept Award to develop novel antimicrobials against Mycobacterium tuberculosis. I am the discipline lead for the Biological and Pharmacological Sciences pillar of the Antimicrobial Resistance Centre.
