Dr. Gary Moran

Associate Professor (Dental Science)

My research focuses on the pathogenicity of oral microorganisms, specifically the fungal pathogen Candida albicans and the oral bacteria Porphyromonas gingivalis and Fusobacterium nucleatum. Our research involves a combination of molecular genetics, genomics and transcriptomics. We also carry out 16s profiling of the oral microbiome to better understand oral disease. Our research is carried out in the Microbiology laboratory at the Dublin Dental University Hospital, which is on the campus of Trinity College Dublin.

My research interests focus on oral microbiology, including: 1) The pathogenic yeast Candida albicans, responsible for oral and systemic fungal infections - I am interested in a telomeric gene family (TLO genes) that encode subunits of the Mediator transcriptional complex. This family of 14 genes regulate virulence traits and we are currently mutating this family using CRISPR-Cas mutagenesis. 2) The oral microbiome: using 16s community profiling identify new disease associations and diagnostic markers in the oral microbiome. Projects include the oral Crohn's disease and Oral cancer microbiomes. 3) Pathogenicity of oral anaerobic bacteria Porphyromonas gingivalis and Fusobacterium nucleatum.
