Billy Bourke

Professor of Paediatrics

Professor Bourke qualified in Medicine from University College Dublin (UCD) in 1988, and received his MD from UCD in 1995. He trained in The Mater Hospital, Dublin, Our Lady’s Children’s Hospital, Crumlin, and The Rotunda, before pursuing a Fellowship in Paediatric Gastroenterology in The Hospital for Sick Children/University of Toronto. He was appointed Consultant Paediatric Gastroenterologist in Our Lady’s Children’s Hospital, Crumlin in 1997.

Professor Bourke’s main laboratory research interest is in infectious diarrhoeal diseases of childhood, and his group focuses particularly on Campylobacter jejuni, a major human intestinal pathogen and the most common cause of bacterial gastroenteritis. Together with a group of close collaborators that includes Professor Ulla Knaus, Dr Marguerite Clyne, and Dr Tadhg O’Croinin at UCD, and the National Children’s Research Centre, Professor Bourke has developed an internationally competitive infection biology research programme that has close collaborative ties with leading national and international scientists in the area of Campylobacter pathogenesis.

Professor Bourke also has an established track record in clinical epidemiology research on digestive diseases of childhood. Together with Dr Marion Rowland, a clinical epidemiologist recognised internationally for her work on the epidemiology of H. pylori, he has a major research interest in the epidemiology of cystic fibrosis-associated liver disease. These studies, funded by grants from the Health Research Board and the National Children’s Research Centre, have focussed on understanding the population incidence and risk factors for the development of liver disease, and its complications among Irish children with cystic fibrosis.

Professor Bourke also collaborates closely with Dr Séamus Hussey, who has set up the DOCHAS project, an ambitious translational research programme that aims to define the epidemiology and biology of Crohn’s disease and ulcerative colitis in Irish children.

Reactive oxygen species targeting the bacterial phosphotyrosine network as defence strategy against mucosal pathogens (NCRC)

We are looking at how reactive oxygen species released by human intestinal cells help protect the gut by disabling bacteria and interfering with their ability to cause infection

Connecting ROS to fibrosis in Crohn’s disease. (HRB)

This study combines research on paediatric specimen with animal studies to understand the redox-initiated progression from chronic inflammation to fibrotic strictures in Crohn’s disease.

Natural History of Cystic Fibrosis Liver Disease – Refining the Phenotype (HRB)

This is a long-term project that has been determine the incidence, severity and outcome of liver disease in Irish children with cystic fibrosis
