About Me
I’m Iris Dominguez-Catena, a postdoc researcher at the Public University of Navarre
(UPNA).
My academic journey at UPNA includes a Bachelor’s degree in Computer
Science (2010 to 2015), a Master’s degree in Computer Science (2018 to
2020) and a PhD (completed in 2024).
I’m currently an Assistant Proffesor at UPNA, continuing my research
on demographic bias and fairness in Artificial Intelligence.
