Research Focus

The Loizou lab is a DNA repair research group. Our vision is to piece together the intricate puzzle that encompasses the human DNA damage response at the cellular level, hence providing a complete understanding of how such pathways go wrong in disease states, with a strong emphasis on cancer.

To achieve this, the team uses genome-scale approaches, based around genetics, genomics, proteomics and chemical biology. We hypothesize, and have proven, that by investigating the regulatory pathways of DNA repair taking unbiased approaches, we can:

1. Advance our knowledge of how cells respond to DNA damage,
2.Uncover genetic interactions required for DNA repair and cellular survival and
3. Unravel the impact on the genome upon engagement of DNA damage and DNA repair pathways. Hence, we envisage that our research will shed light on the mechanisms leading to cellular transformation and pave the way for better treatments for cancer.
