Me

Currently a first year Computer Science PhD student at Aberystwyth University. I completed my Software Engineering MEng at the University in 2011.

This site contains my own undergraduate work, as well as links to a number of useful websites and tools. Within the computer science department I have taught classes on programming with perl and PHP, provided support during laboratory sessions and guided students with their projects in a drop-in advisory service. I have industrial experience developing, testing and deploying back-end code for web-based control panels.

You can find my contributions to the Internet here.

Ph.D Thesis

My thesis, funded by the Prostate Cancer Charity (Aberystwyth University news archive here) concerns improved staging and localisation of prostate cancer through multi-modality data fusion.

Abstract

The fusion/registration of magnetic resonance and ultrasound information can make significant contributions to the initial diagnosis and localisation of prostate cancer, and as such to the staging process (surgery/radiotherapy). In addition, the available information can be used to improve localisation of biopsies and therapy (both the targeting of specific areas and the monitoring of treatment). Current approaches to the fusion of MRI and ultrasound prostate information tend to rely on manual intervention or tracking systems.

We propose to develop a data driven approach to this fusion/registration problem, which will use prostate boundary and internal anatomical region information. The automatic segmentation of these prostate features will be based on shape and texture analysis techniques. The resulting fusion of MRI and ultrasound data will form the basis for the clinical evaluation with respect to the diagnosis and localisation of prostate cancer.

Current Work

I am currently focussed on prostate boundary segmentation in TRUS and MR images.

Presentation material for the PGM0120 research training module is here.
