Funded PhD Project (European/UK Students Only)
Radiotherapy is one of the key tools for the treatment of cancer, given to about half of patients. It is a highly effective treatment, thanks to advanced delivery technology enabling individual tumours to be precisely targeted. However, we also know that there are significant biological variations between tumours that affect how they respond to radiation, which are not currently taken into account in radiotherapy planning. This PhD will take place as part of an interdisciplinary research group seeking to develop models to help us bring our knowledge of the drivers of radiation response towards clinical applications. In particular, this project will focus on developing links between computational models describing how radiation damages DNA within individual cells, and those describing how cells attempt to repair this damage. This link is an important step in the development of new treatment strategies for cancer.
The main way radiation kills cells is through damage to DNA. The amount and type of damage depends on the dose and type of radiation delivered, and is a major determinant of whether cells survive radiation exposure. Recent advances in computational modelling tools (such as TOPAS-nBio) have enabled the prediction of the yield and type of damage caused by different types of radiation from fundamental physics, in detailed models of realistic cell nuclei. Alongside this, other models have been developed to predict how cells
respond to this damage, including models of repair, proliferation and cell death.
However, at present these models are not linked, so it is difficult to examine the full picture of radiation response. Working together with investigators in the Patrick G Johnson Centre for Cancer Research at Queen’s and collaborators as Massachusetts General Hospital in Boston, the successful applicant will develop tools to link these models. This will enable integrated predictions of radiation sensitivity incorporating both physical and biological effects in detail, improving our understanding of how cells respond to radiation exposures.
