I am a Research Fellow and Baily Thomas Doctoral Fellow in the Biostatistics Research Group specialising in 'big data' epidemiology. I have a particular interest in learning disabilities and mental ill-health. I also work on the Virtual Cardio-Oncology Research Initiative (VICORI), which uses electronic health record data to explore differential risk factors, treatments and outcomes among people with cardiovascular disease and/or cancer.


My current research includes:

• A study of life years lost and care pathways in people with learning disabilities: a real-world observational study (Doctoral Fellowship funded by the Baily Thomas Charitable Trust) - Use of linked CPRD data to explore health and mortality inequalities and care pathways among people with learning disabilities.

• The Virtual Cardio-Oncology Research Initiative (VICORI) - Use of patient data to explore differences in risk factors, treatments and outcomes between people with cancer, cardiovascular disease, or both.
