Marcus returned to education as a mature student in 2009, undertaking the BA Connect in Irish Studies, with joint honours in History and Archaeology at NUI Galway. While there, he was awarded a certificate of merit for excellence for his first year results. The final year of the Irish Studies course involved a three-month term of study on Erasmus abroad, which he spent in Leuven University, Belgium. His Irish Studies thesis was titled ‘Sculpture and Commemoration: Bronze Representations of Famine Memory’ which focused on commemoration of the Irish famine through various bronze sculptures in Ireland and abroad. He was awarded a distinction for this paper.
His final year history thesis entitled ‘Recovering Evidence of the Brehon Laws Through Archaeological Enquiry’ dealt with how early Irish Brehon laws could be recovered through archaeological evidence as discovered in recent excavations. Marcus is currently studying for a Masters in Landscape Archaeology at NUI Galway
