Hey there ūüĎč, I am a PhD Candidate in Natural Language Processing and fortunate to be supervised by Dr. Nils Reimers and Prof. Dr. Iryna Gurevych.

I am deeply fascinated by the ability to encode sequential information into Sentence-Transformers representations, enabling emergent properties and behaviors using just cosine similarity. The elegance of representing intricate sequential structures through such a simple yet powerful similarity measure is still stealing my sleep. Apart from my passion on representation learning and retrieval my research interests evolve around:

  • Retrieval-Augmented Generation
  • Synthetic Data Generation
  • Dialog Modeling
  • Efficient NLP

Hobbies:

In my free time I like to spend time outside in nature, either hiking (with my dogs) or mountain biking. You most probably will see me walking around with headphones, not because I am not willing to talk to you but because I am very passionate music listener. (I also play some music, preferred instruments: piano, guitar and drums)
