Dr Zoe Dyson (PhD)

Zoe is a Marie Curie research fellow based at LSHTM in London, focussing on genomic surveillance of the bacteria that cause typhoid fever (Salmonella Typhi). She uses genomic sequence analyses to understand how these bacteria spread within and between geographies and how they evolve drug resistance. Find Zoe on Google Scholar and twitter @msmicrobiocode.

Dr Ebenezer Foster-Nyarko (PhD)

Ebenn is a clinical microbiologist and recently completed a PhD on E. coli genomics. He joined the lab in 2021 to work on the KlebNET Genomic Surveillance Platform, aiming to improve antimicrobial resistance and virulence prediction for Klebsiella pneumoniae to support global genomic surveillance. Find Ebenn on LinkedIn, Google Scholar and twitter @EFosterNyarko.

Dr Kara Tsang (PhD)

Kara is a computational biologist who joined the lab in 2021. She is leading the antimicrobial resistance prediction component of the KlebNET Genomic Surveillance Platform project. Find Kara on Google Scholar and twitter @KaraKTsang.

Tom Stanton

Tom combines microbiology and bioinformatics to study the genetic basis for clinically important phenotypes in Klebsiella and related pathogens. He is currently working with Kelly and Kat on understanding the relationship between genetic variation in the K (capsule synthesis) locus and serotype, and investigating sero-epidemiology of K. pneumoniae. Find Tom on twitter @tomstantonmicro.

Dr Annapaula Correia (PhD)

Anna is working on the KLEB-GAP project with colleagues in Norway and Queen’s University Belfast, applying machine learning and genome-wide association analysis techniques to explore the genetic basis for clinically important features of Klebsiella pneumoniae, including virulence and antimicrobial resistance.

Dr Charlene Rodrigues (DPhil)

Charlene is a paediatric infectious diseases clinician with a PhD in meningococcal genomics. She is currently working on the KlebNET Genomic Surveillance Platform project, where she will contribute to the devlopment of global genomic surveillance for Klebsiella pneumoniae, including applying her expertise in reporting of genomic results for a clinical and public health audience. Find Charelene on twitter @cmc_rodrigues and Google Scholar.

Sydney Miles

Sydney is undertaking a PhD with Kat and Serge Mostowy at LSHTM, under the London Interdisciplinary Doctoral (LIDo) Training Programme. She is combining comparative genomics and in vivo infection modelling to investigate the evolution of pathogenicity and epidemiological success of Shigella sonnei lineages.

Dr Kelly Wyres (DPhil)

Kelly is a NHMRC Emerging Leadership Fellow whose work focusses on understanding the evolution and epidemiology of Klebsiella pneumoniae, in particular how and why this species is subdivided into hundreds of distinct clones that cause different clinical problems.

Dr Margaret Lam (PhD)

Margaret (Maggie) joined the group in July 2015 as an RA before starting as a postdoctoral fellow the following year. In 2022 she commences a NHMRC Emerging Leader Fellowship. Her research in the group has largely focussed on using comparative genomics and computation biology to unravel the incredible genetic diversity and mobilisation mechanisms of key virulence loci in Klebsiella pneumoniae, and her fellowship will focus particularly on the role of plasmids in. Maggie holds a Bachelor in Biomedical Science, Honours in Science and a Doctoral degree from The University of Melbourne. Find Maggie on Google Scholar.

Dr Jane Hawkey (PhD)

Jane joined the lab in 2013 as a PhD student, with a focus on the mobile elements that are responsible for disseminating antimicrobial resistance. During her PhD she developed the software ISMapper for enabling the detection of insertion sequences from short-read sequencing data. After the completion of her PhD in 2017, Jane became a postdoctoral research fellow in the group and in 2021 she joined the MRFF SuperBugAI project team. She is interested in the genomic evolution of hospital pathogens, particularly regarding mobile genetic elements that are shared between species. Find Jane on Google Scholar and twitter @yekwah.

Ryan Wick

Ryan joined the group as a MSc Bioinformatics student in 2014 and submitted his PhD in 2021. His work mainly focuses on bacterial genome assembly with an emphasis on the use of data from Oxford Nanopore’s sequencing platforms. He developed the software packages Bandage, Unicycler, Trycycler and PolyPolish, and also maintains our Kleborate and Kaptive software. His broader academic interests include machine learning, metagenomics and phylogenomics. Find Ryan on Google Scholar, github and twitter @rrwick.

Hassan Al-Mana

Hassan is a PhD student working with Kelly and Kat, using genomic approaches to understand the genetic basis for uropathogenicity of Klebsiella pneumoniae (i.e. how the bacterium causes urinary tract infections).

Hugh Cottingham

Hugh did Honours in the lab in 2020, exploring the potential for using CRISPR-Cas9 coupled with nanopore sequencing for detection and typing of drug resistant Klebsiella. He commenced a PhD project in 2021, working with Kat, Jane, Nenad Macesic and Anton Peleg on nanopore sequencing-based approaches for clinical microbiology in the hospital setting.

Helena Cooper

Helena commenced a PhD program in 2021 with Kelly and Kat, working on metabolic modelling of Klebsiella pneumoniae.

  • David Edwards tragically passed away October 2020. He was a wonderful and generous colleague who will be sorely missed by the other members of the lab. joined the lab in 2010 as a Masters project student, wherein he developed RedDog for bacterial nucleotide variant and gene content analysis, and helped to write the Beginner’s Guide to Comparative Bacterial Genomics. David stayed on in the lab as a research assistant for several years before enrolling as a PhD student, investigating approaches for detecting different types of natural selection in pathogen populations, and developing SNPPar.
