Radboud Universiteit

Faculty of Science
The Faculty of Science (FNWI), part of Radboud University, engages in groundbreaking research and excellent education. In doing so, we push the boundaries of scientific knowledge and pass that knowledge on to the next generation.

We seek solutions to major societal challenges, such as cybercrime and climate change and work on major scientific challenges, such as those in the quantum world. At the same time, we prepare our students for careers both within and outside the scientific field.

Currently, more than 1,300 colleagues contribute to research and education, some as researchers and lecturers, others as technical and administrative support officers. The faculty has a strong international character with staff from more than 70 countries. Together, we work in an informal, accessible and welcoming environment, with attention and space for personal and professional development for all.

Radboud University
At Radboud University, we aim to make an impact through our work. We achieve this by conducting groundbreaking research, providing high-quality education, offering excellent support, and fostering collaborations within and outside the university. In doing so, we contribute indispensably to a healthy, free world with equal opportunities for all. To accomplish this, we need even more colleagues who, based on their expertise, are willing to search for answers. We advocate for an inclusive community and welcome employees with diverse backgrounds, cultures, and perspectives. Will you also contribute to making the world a little better?

1. Introduction

The Department of Mathematics at Radboud University is looking for an ambitious postdoctoral researcher to strengthen its Algebraic Topology group and contribute to an exciting research project in homotopy theory.

2. Job description

As a postdoctoral researcher you will work with Dr Magdalena Kedziorek and Dr Steffen Sagave on a project related to homotopy theory. The position is part of the project ‘Symmetry on the interface of topology and higher algebra’, which is funded by the Dutch Research Council (NWO). You will be expected to communicate your findings through publications in peer-reviewed journals.

You will be encouraged to take part in the activities of the algebraic topology group and the mathematical community in general, by participating in conferences, workshops and seminars. There is no teaching load; however, participation in teaching activities is advised (for up to 10% of your working time). You will mentor PhD candidates and have direct contact with undergraduate students.

3. Profile

  • You hold a PhD degree in mathematics.
  • You have an interest and experience in at least one of the following topics: equivariant homotopy theory, algebraic K-theory, topological Hochschild homology, infinity categories.
  • You have a good command of the English language. 

4. We are

Algebraic topology is one of the research areas of the Department of Mathematics at Radboud University. The field is represented by Magdalena Kedziorek and Steffen Sagave. The department has a friendly and welcoming atmosphere with researchers in related areas including algebraic and arithmetic geometry, differential geometry, operator algebras and representation theory. There is a good balance of senior and junior staff, as well as of Dutch and international researchers, and there are research seminars and informal events throughout the year. Moreover, the algebraic topologists at Radboud University are part of a larger network of Dutch algebraic topologists who regularly interact and meet for seminars and other events.

The Mathematics Department has more than 20 PhD candidates, six of whom currently work in algebraic topology and related areas. The department is an open and supportive environment – members from groups that are underrepresented in mathematics are particularly encouraged to apply.

5. We offer

  • We will give you a temporary employment contract of two years with the possibility of an extension for another year. 
  • Your salary within salary scale 10 depends on your previous education and number of years of (relevant) work experience. The amounts in the scale are based on a 38-hour working week.
  • You will receive an 8% holiday allowance and an 8,3% end-of-year bonus. 
  • You will receive extra days off. With full-time employment, you can choose between 30 or 41 days of annual leave instead of the statutory 20. 

6. Practical information and applying

You can apply only via the button below. Address your cover letter to dr. Magdalena Kedziorek and dr. Steffen Sagave. In the application form, you will find which documents you need to include with your application. We look forward to receiving your application.
