Fulltime vacatures in Haaksbergen

We are looking for an enthusiastic and highly motivated postdoc candidate to join the Mathematics of Computational Science (MACS) group within the Department of Applied Mathematics at the University of Twente as soon as possible. You will work under the supervision of Dr. Gregor Gantner on a project dedicated to advancing the field of adaptive methods for time‑dependent partial differential equations (PDEs). The position is funded by the Dutch Research Council (NWO) via the Vidi research project "Optimal adaptive spacetime boundary and finite element methods."

The project focuses on the design, numerical analysis, and implementation of novel numerical algorithms to efficiently solve parabolic PDEs such as the heat equation. You will investigate space‑time finite element methods (FEM) and space‑time boundary element methods (BEM), develop suitable a‑posteriori computable estimators for the discretization error to adaptively steer the mesh refinement, and mathematically prove that the resulting algorithms converge optimally with respect to the number of mesh elements. You will also implement the methods and validate the theoretical results through numerical experiments.

Research will be conducted in a collaborative, international, and interdisciplinary environment that values academic excellence and open exchange of ideas. The MACS group offers a stimulating atmosphere with regular discussions, opportunities for collaboration, and access to expertise in numerical analysis, dynamical systems, and high‑performance computing. The position includes funding to present your work at leading conferences and engage in international collaborations.

• You have, or will shortly obtain, a PhD degree in Applied Mathematics or a closely related field, with a strong focus on numerical methods for partial differential equations.
• You are familiar with at least one of the following topics: adaptive finite element methods, boundary element methods, or space‑time methods.
• You have proficient programming skills, ideally in at least one of the following languages: Matlab, Python, Julia, or C/C++.
• You are an enthusiastic, highly motivated candidate with a creative and analytical mindset.
• You can work independently while maintaining high‑quality standards.
• You have a good team spirit and enjoy working in an internationally oriented environment.
• You are proficient in English.

• Appointment for a period of 18 months in a stimulating scientific environment.
• Salary and conditions in accordance with the collective labour agreement for Dutch universities (CAONU).
• Gross monthly salary ranging from € 3 546 (step 0) to € 5 538 (step 12), depending on experience and qualifications.
• Benefits include an 8 % holiday allowance of the gross annual salary, an 8.3 % end‑of‑year bonus, and a solid pension scheme.
• Flexibility to work (partially) from home.
• A minimum of 232 leave hours for full‑time employment based on a 38‑hour formal workweek; a full‑time practice of 40 hours a week corresponds to 96 extra leave hours annually.
• Free access to campus sports facilities.
• A family‑friendly institution offering paid and unpaid parental leave.
• Excellent support for research and facilities for professional and personal development.

Applications are accepted until May 21, 2026. Please submit:

• A Curriculum Vitae, including the names of two possible references, a list of publications, and a list of all courses attended with grades obtained.
• A cover letter (maximum 2 pages A4) emphasizing your specific interest, qualifications, and motivations to apply for this position.

The first round of interviews will be held on May 26, 2026. Screening is part of the selection process.

The faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) uses mathematics, electronics, and computer technology to contribute to the development of information and communication technology. Our faculty works closely with industrial partners and researchers in the Netherlands and abroad, conducting extensive research for external commissioning parties and funders. The research activities are housed in multidisciplinary research institutes, including the Mesa+ Institute, TechMed Centre, and Digital Society Institute.
