Dr Alasdair Hubbard

Postdoctoral Research Associate

Graduated with a BSc (Hons) in Microbiology from University of Leeds in 2007 and a Ph.D from St George’s, University of London in 2015. Between BSc and Ph.D, worked at the Health Protection Agency and Dstl, Porton Down.

Post Ph.D worked as a Postdoctoral Scientist at a molecular diagnostic company and a Research Assistant at University of Oxford


My main research interests are based around the use of genomics and experimental evolution to understand the development of antimicrobial resistance in clinically relevant bacteria. I also have an interest in understanding and characterising novel mechanisms of antimicrobial resistance and early stage drug discovery.

Main projects:

Fitness costs of acquired AMR in Enterobacteriaceae: A reduction in the fitness of bacteria has been found to be associated with acquisition of resistance compared to the parent antimicrobial sensitive strain when the antimicrobial is no longer present. We want to take advantage of this fitness cost to minimise the persistence of resistance within the clinical setting and inform clinicians of the optimal treatment options to slow the emergence and spread of AMR.

Discovery of antimicrobial proteins from snake venom: Proteins with antimicrobial properties have been discovered in a wide range of venom. Using an iterative assay, we are screening snake venom from species of snake housed at LSTM to discover proteins with previously unknown antibacterial activity towards Escherichia coli.
