In 1988 he was awarded a Trinity College Foundation Scholarship,[1] where he was also jointly awarded the St Patrick's Benevolent Society of Toronto prize for obtaining the highest overall marks in the scholarship examinations in the university that year.
[1] He was then awarded three scholarships to go to the University of Cambridge for his PhD where he studied the applications of Bayesian methods to digital signal processing.
The work included novel algorithms for audio restoration as well as more general methods for analysing and detecting changes in data.
His postdoctoral work at Trinity College Dublin and at the University of Geneva concentrated on the then-emerging field of digital watermarking.
In 2005 he joined GE Healthcare in Piscataway, New Jersey, where he published four patent applications on optical sectioning, Line Artifact Removal, Brightfield image segmentation and Cell Tracking in microscope images.
