Assistant Professor in Machine Learning & WASP Fellow

KTH Royal Institute of Technology

I am an Assistant Professor in Machine Learning at KTH Royal Institute of Technology, WASP fellow, and a member of the ELLIS society. Before joining KTH, I was an Academy of Finland postdoctoral researcher at Aalto University working with Arno Solin. My research is centred on making machine learning more #reliable by representing, quantifying, and reducing #uncertainty. I am particularly interested in #efficient and #principled approaches for large-scale machine learning models and AI agents.

See biography for more details.

Research Interests

  • Tractable Models: Probabilistic circuits, neurosymbolics, and probabilistic inference.
  • Bayesian Learning: Uncertainty in deep learning, approximate inference, and nonparametrics.
  • Probabilistic Numerics: Low-precision regimes, surrogate uncertainty, and uncertainty propagation.
