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.

Sarah is also Associate Statistical Editor for the Journal of Infectious Diseases.
Collaborating Group Leads
Molecular Biologists and Laboratory
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 projects that aim 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 and Nanopore sequencing platforms.
Teresa obtained both her BSc in Biochemistry and her PhD from the University of Bath.
Sophie is assisting at the lab bench to optimize and develop methodologies for sequencing antibiotic resistance genes in human pathogens.
She explores the medical microbiology field after completing an MSc in molecular ecology at UiT The Arctic University of Norway and assisting in DNA damage repair research at the Genome Damage and Stability Centre in Brighton.

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.
Statistics and large dataset analysis
Phuong is a Research Methodology Fellow and completed her MSc in Applied Statistics in 2013. She conducts epidemiological research using both primary and secondary data sources, with recent projects covering pneumonia incidence and risk factors for urinary tract infections.

Eric Budgell joined the group as a Medical Statistician in April 2016. He currently investigates antimicrobial use and resistance in large observational cohorts in the UK. This work is helping to optimize the design of clinical interventions and randomised studies that will explore ways to reduce antibiotic burden in acute/general care, with the ultimate long-term goal of reducing antimicrobial resistance. Prior to this he worked as an epidemiologist in South Africa and as a consultant to the World Health Organization in Switzerland. He completed his MSc here at the University of Oxford in 2012
Tjibbe Donker is a infectious disease modeller whose research focusses on the influence of health care networks, formed by exchanged patients, on the spread of antibiotic-resistant bacteria and other hospital-associated pathogens.
Sean joined the group in October 2017 after receiving a PhD for work on the chemical biology of pathogens such as P. aeruginosa and E. coli. His research uses large datasets of electronic health records to study infection, resistance and treatment trends in the UK. Specifically, he is investigating whether antibiotic resistance affects clinical outcomes associated with E. coli bacteraemia. Inappropriate treatment of resistant infections is thought to lead to poor patient outcomes, which encourages doctors to prescribe broad-spectrum antibiotics out of an abundance of caution. Nonetheless, there is little compelling evidence that this is an effective use of antibiotics, and the effect of inappropriate empiric treatment remains unclear. This work will support effective clinical decision-making and antibiotic stewardship, benefitting patients and public alike.
Emma joined the group as a Medical Statistician in October 2018. She conducts epidemiological research and is currently investigating what diagnostic codes are used for patients who have bacteraemia. She is also exploring the contribution of sepsis to mortality, and how best to adjust for comorbidities in studies using electronic health records.
Prior to joining the group, she completed an MSc in Medical Statistics at the University of Leicester, where she carried out research into complex genomic variations in the CCL3L1 and CCR5 genes and their potential role in the development and progression of COPD. She graduated from Lancaster University with a BSc in Natural Sciences in 2017.
Other Postdoctoral Researchers
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.

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.
Philip also runs the Citizen Science project BashTheBug which invites anyone to help us tackle tuberculosis by measuring how well different strains grow on different antibiotics. Please see http://bashthebug.net or @bashthebug.
