The Faculty of Science and the Leiden Institute of Advanced Computer Science (LIACS) is looking for a:

PhD Candidate in Algorithmic Fairness in Social Network Analysis (1.0 FTE)

About this position
Are you a passionate and committed young researcher well versed in social network analysis, complex networks or network science? Would you like to be involved in frontier research on algorithmic fairness, biases, and inequalities in large-scale social network analysis in an inspiring academic environment? Effective immediately, at Leiden University, we are seeking a PhD student in Algorithmic Fairness in Social Network Analysis. The candidate will work on analyzing fairness and biases in network-based algorithms, develop fairness-aware algorithms, and design intervention methods to promote fairness in networks.

We are looking for
An excellent young scientist with a MSc degree or equivalent in computer science, data science, computational social science, statistics, physics, mathematics, or a related field. You have a keen interest in algorithms, well-developed skillset 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 new network algorithms and measures. 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 machine learning.

You will be part of the Computational Network Science (CNS) research group (see https://cns.liacs.nl) 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, https://www.universiteitleiden.nl/en/science/lcn2) and nationally through, for example, the Dutch Network Science Society (https://www.netsci.nl).

What will you be doing as a PhD Candidate?

• Conducting research on Algorithmic Fairness in Social Network Analysis, leading to peer-reviewed publications;
• Writing an article-based PhD thesis within the duration of the position;
• Co-supervising BSc and MSc students (Limited involvement);
• Presenting research at international conferences;
• Being an active member of the CNS research group and taking up minor local organizational activities;
• Engaging in a limited number of teaching activities;

Selection criteria:

• A master’s degree* in a relevant field (e.g., computer science, mathematics, physics), ideally with experience in network science, complex networks and/or social network analysis;
• Experience with programming in languages relevant to social network analysis, including at least Python and perhaps also R and/or C++;
• Excellent writing skills and proficiency of the English language;
• Able to work independently and in a team;
• An academic, creative and curious mindset;
• *Candidates not (yet) past the master’s phase are also invited to apply, assuming they will graduate in Summer 2024.

Our organisation
