**About the Special Issue Editors**

**Catherine M´eplan** (Lecturer in genetics). Dr Meplan has worked at Newcastle University, UK ´ since 2003. Her research interests focus on the application of nutrigenomics technologies to the understanding of the relationship between selenium status and various cancers. She has contributed to the discovery of the importance of genetic variations in selenoprotein genes on selenium bioavailability, as well as using combined transcriptomics and proteomics approaches to understand how selenium status affects molecular pathways involved in cancer development. She and Dr Hughes are currently collaborating on several European projects looking at the effects of interactions between inherited genetic variations and selenium status on disease risk. She is a member of the European Nutrigenomics network NUGO, and has worked in collaboration with many research groups on selenium research. Previously, she has worked on the p53 tumour suppressor protein and cancer at the Biomedical Research Centre (Dundee University, UK), and during her PhD in Biology at the WHO/International Agency for Research on Cancer (IARC, Lyon, France). She received her BSc and MSc in Molecular Biology from the University of Grenoble, France.

**David J. Hughes** (Assistant Professor of Cancer Epidemiology). Dr Hughes is a Fellow of the Conway Institute in University College Dublin (UCD), Ireland. He currently leads several international multidisciplinary cohort studies of nutritional, genetic & microbial cancer molecular epidemiology. Dr Hughes is a PI in the European Prospective Investigation of Cancer and Nutrition (EPIC) and a member of its Gastrointestinal Cancer Working Group, a governing council member of the International Society for Selenium Research, and a member of the International Cancer Microbiome Consortium. Previously he has worked at the WHO/International Agency for Research on Cancer (IARC, Lyon, France), the Sanger Institute (Cambridge, England), and Imperial College (London, England). Dr Hughes received his BSc Biochemistry degree from the University of Leeds (England), his PhD in Medical Genetics from Queen's University Belfast (Northern Ireland), and a Postgraduate Diploma in Health Professions Education from the RCSI (Dublin, Ireland).
