Research Interests

  • Inference in Survival Analysis
  • Solutions for the problem of non-proportional hazards and crossing survival curves
  • Methods for factorial designs
  • Resampling techniques (especially Permutation methods) for small sample sizes
  • High-dimensional and functional data


  • mdir.logrank: available on CRAN. This packages contains the flexible combination approach of weighted log-rank-test for the two-sided (Ditzhaus and Friedrich, 2020) and the one-sided problem (Ditzhaus and Pauly, 2019)
  • GFDsurv: avaibable on CRAN. This packages contains three different tests for survival data in general factorial designs (Ditzhaus, Dobler and Pauly, 2021; Ditzhaus, Janssen and Pauly, 2020; Dobler and Pauly, SMMR, 2019).

Supervised Thesis

  • Random survival forests beyond the Cox model: Simulation study for new splitting rules (Bachelor thesis, 2021)
  • Quantile-based MANOVA: A new tool for inferring multivariate data in factorial designs. (Master thesis, 2021)
  • Solutions for the curse of non-proportional hazards: The potential of the net benefit in clinical trials (Bachelor thesis, 2021)
