The University of Potsdam in Germany is offering several funded PhD and postdoctoral positions in the field of Natural Language Processing (NLP) and Computational Linguistics, with a focus on language learning in interaction, simulating situated use, and evaluating large language models (LLM agents) in interaction. The positions are available in the Department of Linguistics, which is known for its collaborative research activities and strong ties to the cognitive science research focus of the university. Openings include a PhD student position (100% TVL-13) with a teaching load, a PhD position (75% TVL-13) within the Collaborative Research Centre 1287 'Limits of Variability in Language', and a postdoctoral researcher position (100% TVL-13) with teaching responsibilities. The research topics cover evaluation of LLMs through conversational games, post-training of models in interaction, and mechanistic interpretation of prompt variability effects. The postdoc role involves joint supervision of students, leading publications, and supporting research project development. Applicants should hold an excellent degree in Computational Linguistics, Computer Science, Cognitive Psychology, or a related field, and possess strong programming and writing skills, intellectual curiosity, and the ability to independently carry out research projects. Postdoc candidates should also have a solid publication record and some teaching or supervision experience. While teaching in German is advantageous, it is not strictly required. Funding is provided according to the TVL-13 scale, with PhD contracts at 75% or 100% and postdoc contracts at 100%, typically for 3 to 3.5 years with possible extensions. Some positions are linked to specific research projects, while others may involve teaching in the university's popular BA and MSc programs in Computerlinguistics and Cognitive Systems. There are also opportunities for self-funded PhD students and research interns, especially for those with external funding sources such as DAAD. The application process is open until positions are filled, with evaluation of applications already underway. Interested candidates should prepare a statement of research interests, electronic copies of degree certificates, a CV with publications and code samples, and references, and send these materials to Professor David Schlangen at the University of Potsdam. For further information, candidates are encouraged to visit the lab's website and contact Professor Schlangen directly.
