James Webster
MSc, PhD
Health Data Epidemiologist
I am a postdoctoral health data epidemiologist with the Applied Health Research Unit in Oxford Population Health. My research aims to answer questions that are most relevant to patients, clinicians, public health policy, and population intelligence using routinely collected health data.
This involves conducting and publishing studies that investigate long-term time-trends in hospitalisation and mortality of diseases to quantify changes in their epidemiological burden; clinical risk factors for diseases; risk of disease after hospitalisation; hospital-related patient outcomes; and variation by geographic region and demographic factors.
My main area of interest is in hip fracture epidemiology. I completed a Masters in Nutrition, followed by a PhD in nutritional epidemiology at the University of Leeds. My doctoral research involved quantifying associations between diet and hip fracture risk using data from prospective cohort studies with linked hospital records.
