Research highlights

  1. Development of the new time series analysis framework of recurrence networks, their use for detection of regime transitions and applications in physiology and climate.
  2. Development of recurrence based coupling analysis, significance assessment of recurrence based data analysis, and recurrence analysis for high-dimensional systems with applications in cardio-respiratory systems, global warming, and monsoon systems.
  3. Complex network analysis of climate data, in particular of extreme states. Identification of characteristic spatio-temporal patterns and teleconnections in monsoon systems as well as development of a prediction scheme for extreme rainfall using the network approach.
  4. Multiscale approach for complex network analysis.
  5. Theoretical justification of complex networks as representatives of atmospheric and ocean circulation. Boundary corrections for spatially embedded networks.
  6. Framework for age-depth modelling of palaeoclimate proxy records and introduction of an “absolute time scale” by transferring dating uncertainties into the proxy domain.
  7. Introduction of the "Transfer cost time series" (TACTS) approach for analysing time series with irregular sampling.
  8. Development of the concept of basin stability for complex networks and application in power grid stability.
