About me

I’m a postdoc at IDEAS NCBR in the Sequential Decision Making group led by Prof. Piotr Miłoś. I’m interested primarily in:

  • Sequential Decision Making – how to use models such as RNNs, transformers, and state-space models in RL and beyond.
  • Fine-tuning RL models – how to harness the power of foundation models in RL by fine-tuning them online.
  • Adaptation in foundation models – how to use LLMs/VLMs in completely new decision-making scenarios.
