Profile

I first joined the Division of Population Health (previously ScHARR) in 2016 after developing an interest in health research methods. Prior to that I completed my PhD in Computational Neuroscience in the Department of Psychology here at UoS. This was funded by the EPSRC and focused on understanding the brain systems and mechanisms involved in human routine action.

Qualifications
  • BSc Psychology (Hons), MSc Cognitive & Computational Neuroscience
  • PhD Computational Neuroscience
Research interests

I am interested in how novel statistical and computational methodologies can help us to exploit routinely collected healthcare data to drive improvements in patient care, particularly in urgent and emergency care and in situations where standard clinical trials may not be possible or feasible. I am also interested in understanding the causal pathways underlying inequalities of access to and provision of healthcare.

Current projects

  • NIHR ARC Yorkshire and Humber Urgent and Emergency Care Theme
  • Reducing Avoidable Admissions in Acute Hospital Care: The role and impact of Same Day Emergency Care Services
  • Mixed methods study to understand the scale, impact and care trajectory for patients who have long life after a fall
  • Integrating genomic and spatial approaches for targeted control of HIV-associated tuberculosis epidemics
