Biomedical Engineering in Ireland (IT Sligo) Group

The IT Sligo group currently comprises two academic staff (Dr John Hession and Dr Leo Creedon), one technical advisor (Gordon Muir) and four postgraduate students.

Members

Research is currently focused in the area of orthopaedics and in particular bone fracture. Postgraduate students are involved in various projects dedicated to these areas, a brief outline of which is given below, for more information

John O’ Toole is using an acoustic emission system to locate the source of bone fractures in bovine bone.

Michael Cafferty is carrying out an investigation into the effects of vibration and fatigue on bovine bone using an in house materials tester.

Robert Carroll is using high speed cameras and an acoustic emission system to investigate the formation of damage in bone. Click here for a recording of cortical bone fracture

Padraig Varley is using a vibration system and a computer modelling package to investigate the effect of fractures in ovine bone.

The laboratory of the Biomedical Engineering Group is equiped with essential equipment for orthopaedic research and is managed by our technical advisor, Gordon Muir. The following is not an exhaustive list of instruments available on site to the research group.

History

The Biomedical Engineering Group was established in 1998 when Dr Brendan McCormack joined the staff at IT Sligo.The group grew when Gordon Muir joined the staff and research commenced in three areas:  analysis of the cutting process of biological materials (lead by Ger Reilly), modelling abdominal activity (lead by Dr John Hession) and cell culturing (lead by Dr Brendan McCormack and Dr Jerry Bird) .The mathematical and statistical research component for the group is led by Dr Leo Creedon.
