The Faculty of Science and the Mathematical Institute are looking for an:

Assistant Professor in Stochastics

The Mathematical Institute at Leiden University in the Netherlands has an opening for an assistant professor in stochastics.

In case of exceptionally qualified candidates, an appointment at associate professor level could be considered.

What you will do

The holder of this post is expected to:

  • (further) develop their own identity as a researcher;
  • acquire national or European research grants to support their own research line;
  • be actively involved in teaching and contribute to the development of our curriculum;
  • (co-)supervise PhD candidates, BSc/MSc students from our programs in Mathematics and MSc students from our program in Statistics & Data Science;
  • contribute to the administrative tasks of the institute.

Where you will work

The Mathematical Institute (MI) is one of the eight institutes within the Faculty of Science and has a strong international orientation. The institute's mission is to push the boundaries of scientific knowledge by developing and applying high-quality mathematics while offering a wide range of mathematical programs in a friendly and intellectually stimulating environment. We believe that mathematics is a fundamental part of human knowledge, and we take pride in our role as guardians of this rich scientific discipline. We are dedicated to expanding the frontiers of mathematical knowledge and applying our expertise to solve challenges in other sciences, society, and industry. Additionally, we actively promote mathematical literacy through various outreach activities.
 
The Mathematical Institute focuses on four key research themes: Algebra, Geometry, and Number Theory; Analysis and Dynamical Systems; Probability; and Statistics and Data Science. There is extensive collaboration between these themes. For more information about the Mathematical Institute, see https://www.universiteitleiden.nl/en/science/mathematics.

What you bring

In this team, we are looking for someone who can work independently. Every job is different, so in the beginning we will devote attention to your onboarding. If some of the work activities are new to you, we will look together at what you need, and draw up a development plan. This position is a good fit for you if you recognise yourself in the following:

  • you hold a PhD in Mathematics or closely related discipline;
  • you have a track record (evidenced by publications in highly ranked journals), preferably with a profile in one of the following two areas:
  • Operations Research
    • Affinity with stochastic and deterministic Operations Research, with ideally a focus on the interface between them.
    • A keen interest, and preferably some experience, in industrial research interactions.
    • An interest in the use of data-driven techniques in Operations Research, and an interest to connect with AI research in the Faculty of Science.
    • Equipped to play a role in the intra-faculty focus area in complex networks.
    • Equipped to teach classes in stochastic and deterministic Operations Research, and to supervise master and bachelor projects.

  • (Applied) Probability
    • Affinity with probability theory, with preferably a focus on physics-inspired models.
    • A keen interest, and preferably some experience, in multi-disciplinary scientific research interactions.
    • Equipped to play a role in the intra-faculty focus area in complex networks.
    • Equipped to teach classes in the broad area of probability theory and to supervise master and bachelor projects.
  • have good communication skills and experience in teaching;
  • have a good command of the English language;
  • have an interest in supporting the Mathematical Institute, through participation in committees and other departmental duties.

 

Additional Requirements to fulfil after hiring
