Portrait of Lars Benedikt Kaesberg

I'm a doctoral researcher at the University of Göttingen focusing on spatial reasoning with large language models. My research explores how LLMs understand and navigate spatial environments, particularly through projects like SPaRC and Spatial Gym.

News

Started as a doctoral researcher at the University of Göttingen, focusing on multi-agent systems and NLP.

Completed my Master's thesis on "Decision Protocols in Multi-Agent LLM Conversations".

Attended ACL 2024 in Bangkok, Thailand to present CiteAssist at the SDP Workshop.

Presented FawnRescue drone project at IdeenExpo 2024.

Publications

My research focuses on multi-agent systems, decision-making in LLMs, and spatial reasoning. I have published 8 papers so far, cited 83 times (h-index 5, i10-index 3). The full list is on Google Scholar.
