During my PhD, I was supervised by Dr Rich Savage (Department of Statistics, University of Warwick), Professor Paul Moss (University Hospital Birmingham) and Dr Keith Roberts (University Hospital Birmingham). My main research interest is machine learning and its applications to problems in medicine, and in particular to problems related to cancer.
PhD Project: Bayesian Methods and Data Science with Health Informatics Data
The main focus of my PhD is pancreatic cancer and its risk factors. Pancreatic cancer is the tenth most common cancer in UK with about 8 800 people being diagnosed every year. It is very difficult to detect and diagnose it as it usually does not give rise to any symptoms or signs in the early stages. The survival rate still remains very low despite the immense effort to find out more about the disease: only 1 % of the patients survive 10 years after being diagnosed.
As part of my PhD, I aim to identify novel pancreatic cancer subtypes, which should lead to a personalised and more appropriate treatment of the disease. I am currently working on the development of novel statistical methods for clustering, with a particular focus on the types and sizes of datasets available in the QEHB informatics system. The applications of these methods should hopefully lead to a more comprehensive understanding of the causes of pancreatic cancer and contribute to the development of targeted therapeutics.
