As a founder member of Fondazzjoni Patrimonju Malti he has helped curate major FPM exhibitions and sourced important artefacts for these exhibitions. Several publications that he has authored have become standard texts for art historians, such as the 1st and the entirely revised and expanded 2nd edition of ‘The International Dictionary of Artists who Painted Malta’. Nicholas is also somewhat of a creative, penning novels and poetry which evoke nostalgia for the Malta of yesteryear.
