Mariana Bento is an Assistant Professor at the Electrical and Software at the University of Calgary. Previously, she served as a postdoctoral fellow in Radiology and Clinical Neuroscience at the University of Calgary. She did her doctorate (2016) in the Faculty of Electrical and Computer Engineering at the University of Campinas with an internship at the University of Calgary, and master's (2013) in the same faculty with an internship at the University of Pennsylvania. She finished her bachelor's in Teleinformatics Engineering at the top of her class at the Federal University of Ceará (2011). Since 2011, she has been working with machine learning, deep learning for medical imaging. Topics of interest are brain abnormalities, heterogeneous datasets, MR imaging quality assessment, and interpretability of deep learning approaches on medical imaging applications.
