Joseph Ó Ruanaidh facts for kids
Joseph Ó Ruanaidh (also known as Joseph Rooney) is a scientist and a frequently mentioned author in the field of digital watermarking. This means he helps create special hidden codes in digital things like pictures or music to show who made them.

Early Life and Education
Joseph Ó Ruanaidh was born in London, England, in 1967. He grew up in Ballyfermot, Dublin, Ireland. He went to the O'Connell School in Dublin.
He studied very hard on his own to get the grades needed to go to Trinity College Dublin in 1986. In 1988, he won a special scholarship called the Trinity College Foundation Scholarship. He also won the St Patrick's Benevolent Society of Toronto prize for getting the highest marks in the scholarship exams that year. In 1990, he finished his Engineering degree at Trinity College Dublin.
After that, he received three scholarships to study for his PhD at the University of Cambridge. There, he learned about using Bayesian inference (a way of using math to make better decisions with data) for digital signal processing. This is about how computers handle and change signals like sound or images. His work included new ways to fix old audio recordings. It also covered general methods for finding and understanding changes in data. His PhD work was even published as a book!
Starting His Career
After his PhD, Joseph worked at Trinity College Dublin and the University of Geneva. He focused on a new area called digital watermarking. He wrote important papers about how to hide watermarks in images. He also worked on watermarks that stay hidden even if an image is rotated or moved.
Career Highlights
In 1998, Joseph moved to the United States. He worked at Siemens Corporate Research in Princeton, New Jersey. There, he helped create a special hearing aid that helps people hear sounds from different directions. This invention was even patented!
In 2000, he joined a new internet company called Certus. This company worked to make online shopping safer for everyone.
In 2005, he started working at GE Healthcare in Piscataway, New Jersey. While there, he filed four patent applications. These patents were for new ways to improve microscope images. This included methods for optical sectioning (seeing different layers in a sample), removing unwanted lines from images, and image segmentation (dividing an image into parts). He also worked on cell tracking, which means following how cells move in microscope videos.
From 2008 to 2010, he worked for the DE Shaw group in New York City. This company uses special computer programs to trade stocks and other financial things. Currently, he works for Apple in Cupertino, California.
His research is often mentioned and used by other scientists. You can see this on websites like CiteSeer, ISI, and Google Scholar.
