About the Mathematical Institute

The institute’s research is driven by the curiosity of its members and has many internal and external connections. It is fundamental but with an open eye for applications. With 45 staff members, 10 postdocs, and 55 PhD candidates (including 3 funded by CSC), it is one of the larger mathematical institutes in the Netherlands. The lively atmosphere is very informal, with everyone from first year students to full professors mingling on a first name basis.

In national evaluations, the institute’s research consistently receive the highest possible scores. The Royal Dutch Academy of Arts and Sciences has 22 members in Mathematics, 9 of which are affiliated to Leiden. This is more than 3.5 times the average number for the nine mathematical institutes in the Netherlands.

Research themes

The research is clustered into four themes:

• Algebra, Geometry, Number Theory
  The research of this group can be described as number theory in the broadest sense, ranging from cryptology to arithmetic geometry and motives, with a strong emphasis on algebraic methods and a direct interest in the computational aspects of the theory.
• Analysis and Dynamical Systems
  The research of this group is centred around functional analysis, noncommutative geometry, and dynamical systems. In particular for dynamical systems, there is a strong interaction between abstract theory and real-world problems in theoretical and computational biology, earth sciences, and physics.
• Probability, Operations, and Dynamics
  The research of this group is in the areas of probability theory, operations research, and ergodic theory/dynamical systems. The group is also strongly rooted in the large national Networks programme, where networks in the broadest sense of the word are studied.
• Statistical Science
  The members of this group carry out research on a broad spectrum of statistical topics, from very applied to very mathematical. These include machine learning and medical statistics.
