Dr. Joseph Ó Ruanaidh (né Joseph Rooney) born in London, England, in 1967, is considered an expert in the field of Digital Watermarking.

In 1990 he was 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. One immediate application, in the Oil Industry, successfully detected a kickback within six weeks of being deployed, when all other detectors failed, thus averting a potentially catastrophic explosion. His doctoral dissertation was published in book form by Springer Verlag.

His postdoctoral work at Trinity College Dublin and at the University of Geneva concentrated on the then-emerging field of Digital Watermarking. He published seminal papers on image transform domain watermarks and, in particular, rotation and translation invariant watermarks based on the Fourier Transform. He also published two patents on the technology.

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. Certus merged with Genuone of Boston, Massachusetts in 2001.

He is currently employed by GE Healthcare in Piscataway, New Jersey, where he has published three patent applications in the past year (2006) on Optical Sectioning, Line Artifact Removal and Brightfield Image Segmentation of microscope images.

His research is well cited as evidenced in CiteSeer, ISI and the Google Scholar.
