Public Profile

Feargal studied microbiology in University College Cork in Ireland for his undergraduate, following this he completed a MSc. in Bioinformatics & Systems Biology. He then began his PhD in the APC Microbiome Institute in Cork. During this time he was involved in several microbiome related projects across the APC including software development and the gut-brain axis, but his primary research was studying the mucosal microbiome of Inflammatory Bowel Disease (IBD) and its interaction with the host by utilizing a combination of metagenomics and RNA-Seq. Upon completion of his PhD he began a post-doctoral position in the Gut Phageomics lab in the APC where he led the bioinformatics team mining the human virome for novel viruses and exploring the role of bacteriophage in the gut microbiome in health and disease. This included developing frameworks for studying the human virome, investigating the impact of birth mode on the infant gut virome and several projects investigating IBD and other conditions. In 2018, he moved to Australia to join David Lynn’s group at SAHMRI where he will be involved in the AIR clinical study to examine the interaction between the microbiome and immune system in early life.
