Research in the Biostatistics Section

Our research is focused on simultaneous inference, and in particular their application in the agricultural sciences, life sciences and genetics. We try not only to develop new methodological approaches, but the associated algorithms as R packages in CRAN. We process deepened sub-themes in the EU FP-7 project, "Embryonic stem cell-based Novel Alternative Testing Strategies, ESNATS" and the DFG-project "Parametric and non-parametric simultaneous inference in complex designs. "
