Igor Rychlik
Professor at
Chalmers, Mathematical Sciences, Applied Mathematics and Statistics
Research areas: Spatial statistics, stochastic geometry and imaging; Reliability of engineering systemsMy primary research interests involve engineering applications of the theory of stochastic processes, especially in safety analysis of structures interacting with the environment, for example through wind pressure, ocean waves or temperature variations. Physical problems often leads to statistical questions that can be extracted and studied independently. My theoretical studies are centred on the description of local properties (wave characteristics) of smooth random processes and fields.
