PhD Position – Spatial structural analyses of crowds

titel

At the Institute for Advanced Simulation – Civil Safety Research (IAS-7) at Forschungszentrum Jülich, we are researching the complex dynamics of crowds. Our goal is to make situations with high density of people - such as train stations, public venues, or events - safer and more comfortable. For the ERC-funded Synergy Grant project CrowdING, we are assembling a new interdisciplinary research team. Together, we aim to understand when and why people change their behavior in large groups—for example, when a crowd that is initially waiting calmly becomes impatient. A team from the fields of physics, computer science, and social psychology is developing new approaches to describe crowd dynamics. The research is supported by large-scale laboratory experiments with numerous participants, state-of-the-art analysis methods and a powerful simulation environment.

Your Job:

In the CrowdING project, you will analyze experimental data from large crowds and develop quantitative measures to describe their spatial structure. To do this, you will use and expand methods such as Minkowski functionals, Voronoi-based density analyses, and modern cluster and pattern recognition techniques. Your goal is to precisely capture the structural characteristics of crowds and investigate how they change under different conditions. The analyses are always carried out in conjunction with social-psychological findings on the perception of crowds, thus contributing to an integrated understanding of physical and social morphology. The work is carried out in close collaboration with project partners at the University of Wuppertal and the University of Groningen (NL). Your tasks will include:

  • Quantitative analysis of experimental data and description of spatial structures in crowds (e.g., Minkowski functionals, Voronoi analyses, clustering methods)
  • Comparison of physical structural analyses with social psychological findings
  • Integration and further development of measurement methods and measurements in the PedPy library
  • Collaboration in the planning, implementation, and evaluation of crowd experiments
  • Exchange and close cooperation with partners from physics, computer science, and social psychology
  • Publication of research results in international journals
  • Presentations at international conferences and participation in project workshops in Wuppertal and Groningen (NL)


Your Profile:

  • Completed university degree (master`s or equivalent) in physics, computer science, mathematics, data science, computational science, or cognitive science
  • Very good programming skills (e.g., in Python, C++, or comparable languages)
  • Ideally, initial experience in the field of crowd dynamics, data analysis, or spatial and temporal movement analysis - however, a strong scientific interest is more important to us than prior knowledge
  • Enthusiasm for combining and expanding methodological approaches and developing new metrics or models
  • Enthusiasm for working in a team and in the interdisciplinary research environment of IAS-7
  • Very good communication skills, also in an intercultural context
  • Very good written and spoken English
  • Structured scientific approach and enjoyment of independently developing models and research methods


Our Offer:

We work on the very latest issues that impact our society and are offering you the chance to actively help in shaping the change! We support you in your work with:

  • MEANINGFUL TASKS: The position offers a varied and diverse role in an international environment and freedom to pursue your own research ideas within the project context
  • KNOWLEDGE & FURTHER TRAINING: Your further development is important to us – we offer a structured research environment with excellent opportunities for scientific advancement
  • SUPERVISION & SUPPORT: We will accompany your doctoral studies with continuous, expert guidance from your academic supervisor
  • WORK-LIFE BALANCE: Optimal conditions for balancing work and private life, as well as a family-friendly company policy. The option of flexible working (in terms of location) is generally available after consultation and in accordance with upcoming tasks and (on-site) appointments
  • VACATION: You will receive 30 days of vacation
  • FAIR REMUNERATION: Depending on your qualifications and assigned responsibilities, you will be classified according to pay group 13 (75%) of the TVöD-Bund. Additionally, you will receive a special payment (“Christmas bonus”) amounting to 60% of one month’s salary. All information about the TVöD-Bund collective agreement can be found on the BMI website (pay scale table on page 66 of the PDF download): https://go.fzj.de/bmi.tvoed
  • FIXED TERM: The employment of doctoral students in Jülich is governed by a doctoral contract, which usually has a term of three years. There is an option to extend the term to four years.
