PhD in Modeling of Cell Migration in Complex ECMs to Decode the Risk for Young Adult Skin Cancer Leiden University in Netherlands

This PhD position at Leiden University offers an exciting opportunity to join the EU PhotoMel project, a multidisciplinary consortium focused on decoding early-life UVA and skincare additive interactions that drive melanoma risk and progression in young adults. The research will be conducted within the Faculty of Science, specifically in the Mathematical Institute and the Institute of Biology, and is embedded in the Multiscale Mathematical Biology (MMB) team and the qBioLeiden initiative. The project aims to develop and interpret novel two-dimensional multiscale mathematical models of melanoma cell migration through complex networks of extracellular matrix (ECM) fibers, with the goal of understanding how UV and chemical-induced ECM changes affect cell migration, proliferation, and gene expression.

As a PhD student, you will further develop simulation techniques for modeling the mechanochemical regulation of melanoma cell migration, integrating these into frameworks such as the Tissue Simulation Toolkit and other CPM platforms. You will design simulation experiments to reflect ECM modifications due to UV and skincare additives, guided by literature, consortium data, and advanced parameter identification methods. Collaboration with a postdoc and experimental biologists, including colleagues at the Medical University of Vienna, will allow you to extend modeling insights to three dimensions and validate models against experimental data from ex vivo human skin samples and organotypic models.

The position is part of a vibrant, international research environment at Leiden’s Bio Science Park, one of Europe’s largest science parks. The Faculty of Science is renowned for its diverse research activities spanning mathematics, information science, astronomy, physics, chemistry, bio-pharmaceutical sciences, biology, and environmental sciences. The Mathematical Institute is internationally oriented and focuses on key research themes such as algebra, geometry, analysis, probability, statistics, and data science. The MMB team specializes in mechanobiology and mathematical biology, working closely with experimental collaborators.

Applicants should have a Master’s degree in theoretical biology, applied mathematics, computational/theoretical physics, computer science, or a related discipline. Strong English proficiency, scientific writing skills, and the ability to work independently in a multidisciplinary environment are essential. Experience in numerical mathematical modeling (e.g., Cellular Potts modeling, particle-based simulations, PDEs, FBA) and programming skills in C++ or a related language are required. The position offers a competitive salary (€3059 - €3881 gross per month), holiday allowance, end-of-year bonus, pension scheme, reimbursement of public transport commuting costs, flexible working hours, generous leave days, home-working allowance, and a university-provided laptop.

Applications are accepted until July 14th, 2026. To apply, submit a letter of motivation, CV, MSc transcripts, a copy or draft of your Master’s thesis, contact details of 1 or 2 former supervisors, and examples of previously written code via the application link. The starting date is flexible, with a preferred start in Fall 2026. For further information, contact Prof. dr. Roeland Merks at [email protected].
