Research areas

Main research interests are focused on antimicrobial resistance and experimental evolution. Specifically, improving the translation of studies on the evolution of antimicrobial resistance (AMR) to clinical practice and understanding the mismatch between phenotypic resistance and the genetic determinants of resistance to improve tools to predict AMR.

Current projects:

Studying evolution of AMR in physiologically relevant environments - Beth James and Alasdair Hubbard

Our primary research focus is to use organoids which represent parts of the human body to study the evolution of antimicrobial resistance to clinically relevant antibiotics in pathogens isolated from clinical samples. Here, we aim to produce robust data on how AMR develops during antimicrobial therapy and use this to guide the use of antibiotics to limit AMR.

Novel mutations leading to beta-lactam/beta-lactamase inhibitor resistance - Hawa Ahmed and Maxwell Jackson

Using multiple approaches, we aim to identify novel mutations which may arise in beta-lactamases which confer resistance to beta-lactam/beta-lactamase inhibitors and characterise the phenotypic properties. This will improve AMR prediction by identifying possible mutations before they arise in clinic.

Silencing and reactivation of AMR genes - Milli Wilde

Silencing of AMR genes can complicate AMR prediction as the gene is present in genotypic data but phenotypically the isolate will be susceptible to the antibiotic. Understanding the silencing and reactivation of AMR genes will give us an important insight into what may occur during antimicrobial therapy.

Relationship between mutational selection windows and collateral susceptibility - Beth James and Sidra Kashif

Mutational selection windows (MSW) can be used to predict the antibiotic concentrations which can select for AMR mutations, while some AMR mutations can result in increased/decreased susceptibility to other unrelated antibiotics. In this project, we aim to determine whether MSWs to one antibiotic is affects the MSW to a second antibiotic and whether this can predict collateral susceptibility networks.
