Biography
He completed his undergraduate and post-graduate studies in Maynooth University, before being awarded a Newman Fellowship in Obesity with Prof Donal O'Shea in UCD and St Vincent's Hospital.
In 2012, he was awarded a Research Fellowship from the National Children's Research Centre and established the Childhood Obesity Immunology Group. He has also been a research fellow in the lab of Prof Lydia Lynch in Harvard Medical School.
The Obesity Immunology Research group focuses on the impact of Obesity on the immune system and the development of co-morbid diseases such as Type II Diabetes and Cancer.
Currently the group is comprised of 3 Post Doctoral Scientists, 3 PhD Students and 2 MD Students.
The group has strong clinical partnerships with Prof Donal O'Shea & Prof Helen Heneghan (St Vincent's University Hospital), Prof Declan Cody (CHI Crumlin) and Dr Anne Marie Tobin (Tallaght Hospital).
The group is funded by grants from the National Children's Research Centre, Health Research Board, Dublin Skin Hospital & Enterprise Ireland.
Research Interests
Ireland has one of the highest rates of childhood obesity in the world. One in four Irish school-going children are living with overweight or obesity, and as a result these children are at a higher risk of developing cardiovascular, metabolic and cancer related co-morbidities later in life. The purpose of our research is to understand how obesity drives this increased risk and aim to develop successful interventions to prevent the establishment of overt chronic disease.
The Obesity Immunology research programme aims to do this by investigating (1) how obesity impacts the immune system, driving inflammation and dysregulation, which underpins the development of the aforementioned diseases. (2) Our research also focuses on how the immune system regulates metabolism (from insulin signalling to adiposity), better understanding of these processes will allow us to identify new therapeutic strategies for obesity and its associated diseases.
To date we have published >60 peer reviewed papers in leading peer-reviewed journals including Nature Immunology, PNAS, Science Signaling, Obesity and The Journal of Immunology.
