Research topics

Medical imaging has grown considerably over the last 20 years, especially with the democratization of MRI in both clinical and preclinical settings. These technological developments have been accompanied by the development of new analytical methods that allow the manual or automatic extraction of quantitative information from these images. Finally, many studies have shown correlations between some of these metrics and a diagnosis or pathological evolution. These metrics are commonly referred to as imaging biomarkers.

My work focuses on the development and validation of novel imaging biomarkers in clinical and preclinical studies. More specifically, my research focuses on i) the development and validation of new MRI acquisition methods, ii) the development of medical imaging analysis methods based on artificial intelligence tools such as machine learning and/or deep learning, and iii) the development of software tools to facilitate the routine preclinical and clinical use of all these developments. Although the majority of my published work focuses on MRI and glioblastoma (preclinical/clinical), my current and future research will focus on other imaging modalities (including CT) and other pathologies (traumatic brain injury and stroke).
