Former Rose of Tralee Aoibhinn Ni Suilleabhain has graduated from Trinity College with her PhD.
The stylish partner of Ryan Tubridy was doing her doctorate in mathematics at the Dublin university, and can now be referred to as Dr Ni Suilleabhain.
The 30-year-old was clearly delighted with her achievement, tweeting "You can call me Dr - just passed my PhD viva :)".
The Mayo native gave up her presenting job on Getaway, the RTE travel show in 2011 in a bid to focus more on her education. For three years, Aoibhinn worked in St Mark's Community School in Tallaght teaching mathematics and science.
She graduated with a first-class honours from UCD in 2005, having studied theoretical physics. She planned to go on to do a Masters right away, followed by a PhD, but had to postpone the plans.
That August she won the Rose of Tralee title.
Aoibhinn and the RTE star last year moved into a €1.25 million house in South Dublin area of Monkstown. It is the first time the couple have lived together and their new home comes with four bedrooms, a huge country-style kitchen and a grand stone hallway leading into the 2,600sq ft property.
Aoibhinn has also been spending her time teaching at UCD, with the College recently confirming the announcement with a post online.
"Aoibhinn Ni Shuilleabhain is taking up the position in mathematics education in the School of Mathematical Sciences, College of Science in UCD," a spokesperson for the college's School of Education said.
Her role is lecturing undergraduate science students as part of a five-year BSc and Masters course.
