Research Interests

I am interested in studying allelic imbalance in gene expression, a common feature of our genome. Due to regulatory polymorphisms, which can occur both in cis- and in trans-, a large number of our genes are preferentially expressed from one allele. This unequal expression can contribute to susceptibility to common diseases. My main aim is to try to use this concept to develop a new method to study predisposition to breast cancer. Additionally, I am investigating the role that this imbalance can play in tumour biology, namely in the effect of mutations and treatment response.
