About the Group

What we do 

We are interested in how gene loss rewires tumour cells and how this may be exploited to target them therapeutically. A particular focus of the group is the identification of synthetic lethality - a phenomenon whereby mutation of one gene renders tumour cells especially sensitive to the perturbation of a second gene. We have developed computational methods to identify synthetic lethal interactions from genetic screens and interpret them using protein-protein interaction networks (see our resource www.cancergd.org). Through the integration of whole proteome expression profiling (see bit.ly/brca_complexes), protein interaction mapping, and high-content screening we are hoping to gain a mechanistic understanding of how gene loss rewires molecular networks. We anticipate that this will aid us in the identification and mechanistic interpretation of novel synthetic lethal interactions. In collaboration with Prof. Walter Kolch we are applying similar approaches to understand how gene loss can lead to drug resistance in BRAF mutant melanoma 

 

Work with us 

We will shortly be advertising positions for a computational PhD student and a lab-based research assistant. For the PhD studentship some programming experience is required and someone with an undergraduate degree in computer science, statistics, genetics or bioinformatics may be suitable. A background in biology is not required for this role. If you are interested in either position, please send me an email and we can discuss further. 

I am also interested in supporting applications for PhD studentships - either through the Irish Research Council’s postgraduate schemes or the UCD School of Computer Science PhD Scholarship Programme. The next deadline for the Computer Science PhD Scholarship is May 2019.
