“Science is not a collection of facts, but a constant struggle with […] nature.” – Judea Pearl

Thanks for your interest in my research.

I am a statistician working on reliable machine learning. In particular, I try to incorporate epistemic modeling uncertainty into adaptive machine learning methods such as self-training, superset learning or Bayesian optimization.
