Tel: 2214916


2001-2002 Bird Foundation Europe Onlus Institute for Rare Diseases ¿M. Baschirotto¿, Vicenza, Italy Scholarship - Research and Diagnostic on rare diseases.


2004 -at present Centre for Colorectal Disease, Education & Research Centre, St. Vincent¿s University Hospital, University College Dublin

My role would include the coordination and management of day to day activities of the colorectal research group. This involves the organisation of the lab, bio-banking and lab maintenance as part of a multi-disciplinary centre. I am also involved in development and setting up of multiple research projects within the group
