Tiarna is a third year PhD student at the School of Biomedical Engineering & Imaging Sciences. Her research focuses on evaluating fairness and biases in Artificial Intelligence (AI) used for cardiac imaging. In her work, she has found that models trained with imbalanced datasets have a worse performance on underrepresented subjects, often minority ethnicities and females. She is currently aiming to find the sources of these biases so that she can then find a method to address and mitigate them.
