Hi 👋, I’m Luis, a first year PhD student at RWTH Aachen University under the supervision of Christopher Morris.
I’m interested in studying the capabilities and limitations of general-purpose machine learning architectures in the context of graph learning. My current research focus is on deriving a principled understanding of graph transformers and their potential benefits over GNNs. Email:luis.mueller@cs.rwth-aachen.de.

Attending to Graph Transformers
Luis Müller, Michael Galkin, Christopher Morris, Ladislav Rampasek
We propose a taxonomy of graph transformers, overview their theoretical properties and investigate experimentally how well graph transformers can recover graph structure and mitigate issues with over-smoothing and over-squashing.
