The Faculty of Science and the Leiden Institute of Advanced Computer Science (LIACS) are looking for a:
PhD Candidate in AI for Network Analysis (1.0 FTE, 4 years)
About this position
Are you eager to contribute to cutting-edge research at the intersection of AI and network science/social network analysis in a vibrant academic environment? Leiden University invites applications for a PhD position in AI for Network Analysis, starting as early as September 1, 2025.
We are looking for a motivated and talented early-career researcher with a strong interest in social network analysis, complex networks, or network science, and relevant background knowledge on methods in machine learning and AI. The successful candidate will focus on innovating the field of network analysis with AI methods. Examples of topics include algorithmic fairness in network analysis, developing network embedding frameworks for real-world network datasets or AI models based on agentic LLMs for simulating real-world network data. The candidate is furthermore encouraged to propose their own research direction related to AI methods for advancing network analysis.
We are looking for
An excellent young scientist with a master’s degree or equivalent in computer science, data science, AI, computational social science, or a related field. You have a keen interest in algorithms, ML, and AI, well-developed skill set in (scientific) programming, and an affinity with network analysis in particular. You are able to work with very large data and have the creativity and curiosity to develop AI models for network analysis. The ideal candidate has a critical, open-minded, and collaborative spirit; is creative, precise, and does not shy back from entering new scholarly terrain at the cutting edge of network science and AI.
You will be part of the Computational Network Science (CNS) research group of LIACS, the computer science and AI department of the Faculty of Science at Leiden University. The candidate will be encouraged to collaborate on projects with other members of the group, which has access to a large number of relevant open and proprietary network datasets and a wide range of expertise, both in applied and fundamental network science research areas. Moreover, there are ample opportunities to collaborate with other research groups at LIACS, for example, data science, text mining, and algorithms. LIACS has an active PhD community that organizes seminars and social events specifically for PhD students. Additionally, there are plenty of opportunities for interaction and academic collaboration with other researchers in network science. For example, faculty-wide through the Leiden Complex Networks Network (LCN2) and nationally through, for example, the Dutch Network Science Society.
