Professional Experience
Dr David Hughes joined the group in October 2011. His current research focuses on cancer genetic, nutritional, and microbial epidemiology and genetic biomarkers for colorectal cancer (CRC). He received his B.Sc. Biochemistry degree from the University of Leeds. Afterwards, his first research post in 1991-1992 was as a research assistant to Prof John Hardy at St Mary’s Medical School, Imperial College London (genetics of Alzheimer Disease). During this time, the group confirmed that mutations in the amyloid precursor protein gene (APP) gene can cause AD, the first gene linked with this disorder. He then did his PhD in Medical Genetics at Queen’s University Belfast. His thesis work involved mutation characterization and haplotype analysis of the CFTR gene, variants of which may cause cystic fibrosis (CF). Dr Hughes’s first postdoctoral positions involved a short fellowship studying atypical cases of CF at the Institute for Human Genetics in Hanover Medical School, Germany and then a two-year post (1998-2000) to begin functional genomic projects on the model nematode, C. Elegans as part of the post-sequencing efforts of the C. Elegans genome in the group of Prof John Sulston at the Sanger Institute, Cambridge, England. From 2000-2006 he was employed as a scientist at the World Health Organization’s cancer research headquarters (the International Agency for Research on Cancer in Lyon, France). His work there primarily concerned the genetic epidemiology of breast cancer (BC). As part of this work, the first confirmed genetic modifiers of the BRCA genes and BC susceptibility in general were located. Dr Hughes returned to Ireland in 2007 where he worked as a research fellow at Trinity College Dublin (Department of Clinical Medicine) until his move to the RCSI. He was instrumental is setting up the CRC genetic research projects at the AMNCH Trinity site.
