The aim of my PhD is to determine if individual characteristics can be identified that are associated both with prostate cancer and PSA. Subsequently, I aim to determine if these characteristics can be accounted for when using PSA as a screening test for prostate cancer, hopefully improving PSA as a test for prostate cancer. A systematic review with standard and individual participant data meta-analyses provide the basis of the initial analyses, with multi-parameter evidence synthesis and Mendelian Randomization providing additional information.

During my PhD, I have also been involved with two systematic reviews and meta-analyses, and have developed a novel method of synthesising data that can't be meta-analysed - the albatross plot.
