- In brief
Many real-life systems and processes are dynamic and essentially stochastic. Examples can be found in areas like communication and information systems, biology, geo-physics, finance and economics, production systems, maintenance, logistics and transportation. Our group develops and studies stochastic and statistical models that yield fundamental understanding and enable control and optimization of such systems. Analysis of these models relies on techniques from fundamental probability theory, queueing theory, stochastic scheduling, spatial stochastics and stochastic geometry.
The research group is internationally well-known and embedded in different national and international research communities. The group organizes two nationally oriented regular seminars, which act as broad and integrating forums for researchers and practitioners in the field of fundamental and applied probability theory.
The group covers a broad range of research areas in (applied) probability theory, providing a unique opportunity for synergy between the different fields of expertise. The goals for the next few years are to further strengthen the national and international research reputation of the group and to provide an active and stimulating environment for young talented researchers. In addition, the group aims to actively transfer knowledge to society through publications and presentations in leading international journals and conferences, as well as by lecturing at universities, consultancy for industry and governmental institutes and teaching courses for companies.
The team aims at striking a good balance in performing both fundamental and applied research. To structure the range of research areas the group is subdivided in three main areas:
- Performance analysis of information and communication system (ST1)
- Probability and spatial stochastics (ST2.2)
- Stochastic geometry (ST2.3)
Leader of the group is Bert Zwart.
