In 1990, he graduated with a degree in Engineering from Trinity College Dublin.

Career He moved to the United States in 1998, where he worked at Siemens Corporate Research in Princeton, New Jersey and where he played a key role in the development of the patented Siemens directional hearing aid.

In 2000, he joined Certus, an Internet start-up, dedicated to making Internet shopping safe.

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.

He was employed by DE Shaw group, a proprietary trading firm based in New York City, from February 2008 until February 2010 and by Apple Inc. from 2016 - 2020. He currently works as a principal algorithm engineer at Singular Genomics.
