Prof Theodoratou’s research interest is on colorectal cancer epidemiology. Her research group focuses on projects in genetic, molecular and clinical epidemiology.

There are currently three major areas of interest in the group:

1. One of the main lines of research in Theodoratou's group is to improve colorectal cancer identification from population screening and diagnostic pathways for symptomatic populations. The ultimate target is to reduce colorectal cancer death rate through improving survival outcomes and the patient journeys for those with symptoms that might indicate colorectal cancer. To explore this the team will develop and evaluate risk prediction models for targeted CRC screening, follow-up and treatment.

2. Another active area of the group is the application of the phenome-wide association study methodology (PheWAS) to investigate the associations between single nucleotide polymorphisms related to biomarker levels (vitamin D, uric acid) and multiple clinical outcomes using data from the UK Biobank. A large number of genome wide association studies have been performed that led to the identification of genetic polymorphisms that increase the risk of disease development. PheWAS is an alternative and complementary approach that has recently been developed to query genotype-phenotype associations.

3. Prof Theodoratou is interested in developing and applying new research methods in relation to empirical research and evidence-based medicine. For example, with colleagues from Stanford University (Ioannidis JP) and Imperial (Tzoulaki I) she has been working on a number of umbrella reviews of risk factors in relation to multiple health outcomes and traits.
