PhD student in machine learning, interested in graph neural networks.

Fabian Jogl

I am a third-year PhD student at TU Wien advised by Thomas Gärtner. My research interests lie in the intersection of machine learning and classical algorithmics. Currently, I am focusing on the expressiveness of graph neural networks. My goal is to perform research that combines applied machine learning with a strong theoretical and mathematical basis.
