Research Interests:
Work in the lab is focused on understanding the cellular responses to DNA damage. Understanding these processes is important for a number of reasons. First, genomic instability is associated with increased risk of cancer. A number of tumour suppressor proteins such as p53 and BRCA-1 function to maintain genomic integrity so defects in these processes are essential to understand cancer. Second, radiation and chemotherapy target tumours by causing lethal DNA damage in tumour cells. The success of these therapies is determined through a series of complex cellular processes including DNA repair and apoptosis. Fully understanding the interplay amongst these processes is important to predict therapeutic responses. As our understanding of these processes increases through our basic science studies, we develop novel therapeutic strategies that we can subsequently evaluate in the lab.
