Tunnel between Newman and Tierney buildings in autumn

The Molecular Epidemiology of Cancer (MEC) Lab, led by Dr. David Hughes, is located at the UCD Conway Institute. Our lab focuses on understanding the epidemiological associations between nutritional, genetic, metabolic, microbial, and lifestyle factors in the initiation and progression of gastrointestinal cancers.

We investigate how these factors contribute to cancer risk and progression using advanced molecular and statistical methodologies. Our research aims to uncover critical mechanisms that influence cancer development.

Our goal is to provide valuable insights that could improve early detection, and prevention strategies for gastrointestinal cancers.

Our Research Areas

Our research aims to integrate molecular epidemiology into population-based medicine, bridging biology, public health, and research. We investigate how dietary, metabolic, genetic, and microbial factors interact in the development of gastrointestinal cancers, with a particular focus on colorectal, hepatobiliary, and pancreatic cancers. Early detection is key to improving outcomes and guiding personalized treatment plans. Using long-term cohort studies, molecular biology techniques and biomarker discovery approaches, we identify risk factors and early warning signs associated with cancer development. Our research can be used to inform early detection, risk stratification, and prevention strategies for certain cancer types.

Research Interests

Our current molecular epidemiology research examines how nutritional, genetic, metabolic, microbial and lifestyle factors (together with their interactive impact on molecular mechanisms) may affect the initiation and progression of gastrointestinal cancers.

Our ambition is to help integrate cancer molecular epidemiology as a vital bridge of population-based medicine linking lifestyle information, cancer biology (including trans-omics datasets), and public health and clinical measures of disease prevention and control.

Our investigative approaches utilize large, international population cohort infrastructures and patient cohort studies.

See for example Dr Hughes' presentations on nutrient research and microbiome research.
