Medical Image Analysis, Graph Neural Networks, Representation Learning, Pattern Recognition

My research goal is to solve the problem in the wide-range of medical data domain by leveraging machine learning techniques. I am interested in how technology can be optimized to mitigate various domain- specific tasks.

Identifying of abnormal cortical sulcal patterns on patient with various neurodevelopmental disease and brain malformation by utilizing the deep prototype-based graph neural networks. Further improvement can be achieved by applying the normative modelling on tons of typical developmental subjects (in progressing).
