Group Leads

Derrick Crook

Professor Derrick Crook qualified in medicine in 1977 at the University of Witwatersrand South Africa; he specialised in General Internal Medicine and Infectious Diseases at the University of Virginia, Tufts, New England Medical Center, USA. He became a Fellow of the Royal Colleges of Pathology and Physicians in 1998, a Professor of Microbiology in 2008 and obtained NIHR Senior Investigator status in 2009. He worked as a NHS Consultant in Infectious Diseases and Clinical Microbiology for the Oxford University Hospitals NHS Trust, and led the Infection Control Department. In 2015 he was appointed Director of Microbiology at Public Health England, and divides his time between this and continuing his commitments leading Modernising Medical Microbiology.

During the past 5 years developed a research programme in translating whole genome sequencing of pathogens and linkage of patient data contained in hospital databases. By linking whole genomic typing of pathogens with this patient data, his research is leading to more rapid and effective diagnosis, management and tracking of common infections such as MRSA, C. difficile, TB and Norovirus.

Tim Peto

Professor Tim Peto is a Professor of Medicine at the University of Oxford. He is the co-leader for the Infection Theme of the Oxford Biomedical Research Centre and a National Institute for Health Research Senior Investigator.

His research has included combination therapy for AIDS, the search for an effective AIDS vaccine, the transmission of methicillin-resistant Staphylococcus aureus in hospitals, and transmission mechanisms for Clostridium difficile infections.

Sarah Walker

Professor Sarah Walker has worked with the group since April 2006, originally on secondment from the MRC Clinical Trials Unit, but part-time with the University of Oxford from December 2011. Her work includes the design and analysis of studies investigating the epidemiology and management of infectious diseases (including healthcare-associated infections) and antimicrobial resistance, predominantly within the “Modernising Medical Microbiology” Consortium translating new whole genome sequencing approaches into microbiology practice and service. Sarah is also Associate Statistical Editor for the Journal of Infectious Diseases.


Collaborating Group Leads

Daniel Wilson

Daniel Wilson is a Sir Henry Dale Fellow at the University of Oxford, where his laboratory investigates pathogen evolution and epidemiology via whole genome sequencing. He is a collaborator in the Modernising Medical Microbiology consortium whose aim is to harness genomics for microbiological diagonostics and infection control in hospitals. His work currently focuses on the identification of genetic variants in pathogen genomes that explain differences in the frequency and severity of infections, in particular hospital-associated infections including Staphylococcus aureus, Clostridium difficile and norovirus.

He has previously held positions at Lancaster University and the University of Chicago.

Zam Iqbal

Zamin Iqbal is a computational biologist at the Wellcome Trust Centre for Human Genetics. Many of the abilities of bacteria and parasites,
such as the ability to avoid the human immune (i.e. defence) system or to not-be-killed by antibiotics, are determined by their DNA. In particular, they commonly “shuffle” their DNA, either by passing chunks between “individuals” (as if you gave some of your DNA to someone on the bus) or by "scrambling" their own DNA. This means that techniques that work for human genetics, where you can (mostly) just compare anyone’s DNA with a fixed “reference”, do not work for bacteria – they are just too different. Zam develops computational methods for comparing bacterial DNA. Some of this work is quite abstract, and some of it very pragmatic, such as this app for telling a doctor whether a patient’s infection is drug-resistant : https://www.youtube.com/watch?v=pM4yiirQD0c.


Molecular Biologists and Laboratory

Teresa Street

Teresa’s research interests lie in the ability to utilise molecular techniques to improve the diagnosis of bacterial infections. Using whole genome sequencing techniques she is working on a project that aims to identify pathogenic bacteria directly from clinical samples, without the need for an initial culture step. Her interests have always been centred on high-throughput laboratory techniques and sequencing. Previously, Teresa has worked on gene expression profiling and re-sequencing projects using microarray technology.

Her current work uses a metagenomics sequencing approach to identify pathogenic organisms causing prosthetic joint infections, using both the Illumina Miseq sequencing platform and, more recently, Nanopore sequencing.

Teresa obtained both her BSc in Biochemistry and her PhD from the University of Bath.

Rosalind Harding

My research investigates the evolution of genetic diversity in human and bacterial populations, with a current focus on bacterial species that have high profile clinical significance in the UK. I use an interdisciplinary approach that combines statistical population genetics, medical microbiology and biological anthropology, and I collaborate with researchers located in the Oxford Departments of Zoology and Statistics and at the John Radcliffe Hospital. We want to understand how antibiotic resistance and pathogenicity emerges from benign human commensal species, and how rapidly can newly evolving lineages attain a global reach across human host populations.

Other Postdoctoral Researchers

Clara Grazian

Clara is a Postdoctoral Scientist who has joined the group in January 2017, after completing a double PhD in Applied Mathematics and Statistics in Université Paris-Dauphine and Sapienza Università di Roma, where she studied methods to perform Bayesian inference for complicated models, such as dependence and mixture models. She is currently involved in studying the mechanisms of development of drug resistance in Mycobacterium Tuberculosis, by using genome-wide association studies. In her work, she tries to use both frequentist and Bayesian methodologies to work with large datasets.

Philip W Fowler

Philip is a Senior Researcher at the University of Oxford. He is a computational biophysicist and is leading efforts to predict by simulating the protein-antibiotic complex whether novel mutations are susceptible or resistant to different antibiotics. Examining the genome of a bacterium to determine its susceptibility to different antibiotics currently relies on knowing the effect of each genotype; hence being able to predict the effect of previously unseen mutations will further improve the utility of whole-genome sequencing based clinical microbiology.

He is experienced at using a wide range of High Performance Computing, including clouds and conventional clusters and is also a Software Carpentry Instructor. Before joining the group he worked in the Department of Biochemistry for ten years.
