Hello,
I am Robert Jankowski, a researcher working on network geometry and machine learning
Postdoctoral Fellow at TU Delft.
Research interests
- network geometry
- hyperbolic embeddings
- machine learning
- graph neural networks
- TDA
I am a Postdoctoral Fellow at TU Delft, working with Maksim Kitsak on shortest paths in large incomplete networks. I received my PhD in network geometry from the University of Barcelona, where I studied network embeddings in multidimensional hyperbolic spaces with Marián Boguñá and M. Ángeles Serrano.
