Xiaowu Sun

Xiaowu Sun holds dual affiliations at EPFL: as a Researcher in the Chair of Mathematical Data Science (SB/MATH/MDS1) and a Postdoctoral Researcher in the Signal Processing Laboratory 4 (STI/IEM/LTS4). Their work bridges machine learning, signal processing, and biomedical imaging with applications in cardiovascular analysis and medical AI.

Research focuses on deep learning-driven approaches for medical image analysis, particularly in cardiac MRI segmentation, predictive modeling of cardiovascular events, and explainable AI systems for clinical decision support.

Publications highlight innovations in graph neural networks for coronary angiography analysis, transformer-based feature fusion in 4D flow MRI, and contrastive learning for echocardiographic view integration.
