Matthias Fey is a third-year PhD student at the computer graphics lab at the TU Dortmund University, Germany. His main area of research lies in the development of new deep learning methods that can be directly applied to unstructured data such as graphs, point clouds and manifolds. Furthermore, he is the creator of the PyTorch Geometric library, which aims to bundle many of the proposed methods in this area to make research more accessible, comparable and reproducible. Matthias studied Computer Science at the TU Dortmund where he received his B.Sc in 2013 and Master in 2017.
