Senior Research Scientist

Google Brain

I am a Senior Research Scientist at Google Brain. I obtained my PhD at the University of Amsterdam working with Max Welling. For my PhD thesis on Deep Learning with Graph-Structured Representations I received the ELLIS PhD Award 2021. I am broadly interested in developing and studying machine learning models that can reason about the rich structure of both the physical and digital world and its combinatorial complexity. This includes topics in graph representation learning, object-centric learning, and causal representation learning.

Note: This hasn't been actively updated in a while. Follow me on Twitter for latest updates. See my talk on Learning Structured Models of the World for an overview of my recent work.
