I am driven by the love for automation and making complex algorithms more accessible. Further interests are robotics, automated machine learning (AutoML), hyperparameter optimization (HPO) and especially Bayesian Optimization (BO) as well as reinforcement learning and meta-learning.

I am also one of the developers of our HPO package SMAC.

Research Interests

  • Dynamic Algorithm Configuration
  • Bayesian Optimization
  • Contextual Reinforcement Learning
  • Meta-Reinforcement Learning
