PhD student in Computer and Systems Sciences, with a focus on Natural Language Processing and Large Language Models

The Department of Computer and Systems Sciences. With over 200 employees and 4,500 students, the Department of Computer and Systems Sciences (DSV) is a strong and dynamic research and educational environment. The discipline of computer and systems sciences bridges the gap between technology and the humanities, social sciences, and behavioral sciences, with great relevance to our lives today and in the future. Our research addresses how new information and communication technology should be designed to benefit people, organizations and entire societies.

DSV offers a stimulating research community in an international environment. As a doctoral student at DSV, you study together with many other doctoral students, collaborate with senior research colleagues and get connected to other researchers in Sweden and abroad. DSV’s current location is Stockholm University's campus in Kista, north of central Stockholm, and we will move to the main Frescati campus within a couple of years.

Project description

You will conduct research in natural language processing, with a focus on large language models (LLMs) in one or more of the active areas of the NLP Group. Possible directions include privacy-preserving learning, explainability & interpretability, reasoning & agentic AI, domain transfer & specialization, and resource-efficient methods. Your research may involve both developing novel and generalizable NLP methods and investigating the limitations of current LLMs, particularly with respect to privacy, reliability, and transparency. You will also explore impactful applications in healthcare, law, and/or education – domains where NLP can provide significant societal benefit.

The position offers ample opportunity for interdisciplinary collaboration with both NLP researchers and domain experts. Together, we aim to advance the responsible and trustworthy use of LLMs in critical real-world contexts. The precise research focus will be shaped collaboratively between you and your supervisors, allowing flexibility to pursue areas aligned with your interests and emerging developments in the field.

In addition to a competitive salary and wellness benefits, you will receive strong support for your academic development, including funding for books, conference travel, and professional growth opportunities. You will join a dynamic research environment with access to international networks, collaborative projects, and mentoring throughout your PhD journey.
