Probability, Operations, and Dynamics


The information below concerns courses that our group teaches in Leiden. 

During the bachelor phase, the language of stochastic reasoning and the key principles behind randomness and complexity are taught. During the master phase, a variety of specific topics is covered at the frontline of modern research. This training allows students to confront some of the most challenging problems in science, technology and society, and prepares them for a career in academics, industry, business or administration. People who are trained in dealing with complexity, uncertainty and risk, and who have the skill to analyse theories, experiments and data, are in great demand worldwide.   

A broad palette of introductory and advanced courses is offered in each of the three POD-areas, with a core programme of courses that are available each year (either mandatory or optional), and a flanking programme of courses that are available every two or three years. The curriculum aims to prepare students to face the most challenging questions surrounding complex systems and stochastic dynamics, both theoretical and applied.
