I am a PhD student in Computer Science (Artificial Intelligence) at the Laboratoire d’Informatique de Paris Nord (LIPN), Université Sorbonne Paris Nord. My research centers on the development and implementation of self-supervised Deep Learning frameworks, with a particular focus on 3D segmentation and reconstruction of anatomical structures in medical imaging. As a laureate of the EUR PNGS-M&CS excellence scholarship, I completed my Master’s degree in 2023. Throughout my academic and research journey, I have cultivated a versatile technical background by working with diverse data modalities, including natural language, remote sensing time series, and medical imagery.
