Dr Garnett is a Reader in Microbial Structural Biology in the Centre for Host-Microbiome Interactions.

A major focus of his work has been understanding the molecular mechanisms that promote disease using structural biology coupled with microbiology, biochemistry, and biophysical techniques.

He gained his PhD from the Astbury Centre for Structural and Molecular Biology at the University of Leeds where he studied transcriptional regulation of L-arginine metabolism in bacteria. After his PhD he remained in Leeds working towards the development of new antibacterial compounds directed against peptidoglycan biosynthesis. He then moved to Imperial College London, where he studied important and novel virulence mechanisms used by bacteria, fungi, and protozoa. After receiving an MRC new investigator award, he moved to Queen Mary University of London in 2015 to setup his research group and to study mechanisms of type II secretion in Legionella pneumophila. He started at King’s in 2019 as a Senior Lecturer and become a Reader in 2022.
