SFB 1232 - From colored states to evolutionary structural materials (German Homepage)
The Collaborative Research Centre (SFB) aims to derive new experimental methods for the development of materials. The general goal is to find target-oriented compositons and process chains that provide material with specific requirments. The main task of our group is to find efficient experimental designs for the development and investigation of suitable descriptors (surrogate parameter) for material properties. We are part of subproject P02.

Quantification of treatment effect variability in clinical trials
The goal is to develop advanced statistical methods for an estimation of patient-wise treatment effect variability and to investigate its utility for the interpretation of subgroup analyses in clinical trials.
Project members: André Lüschen and Werner Brannath (PI)
Research Funding of University Bremen - Focus Project
Non-parametric and semi-parametric inference for complex multi-state data under the semi-Markov and the non-Markov assumptions. The utiltity of advanced statistical methods for the analysis of data from longitudinal (observational) studies with structured diaries is investigated. An example is the PAMINA study where migraine patients wrote a daily diary for about 3 months containing information on potential migraine trigger factors and medication. The focus of the investigation will be on multi-state models (Markov and non-Markov) and statistical methods for causal inference.

Past Projects
Design and Analysis of three- and multi-armed "gold-standard" non-inferiority trials
The statistical methodology for placebo controlled non-inferiority trials was further developed. A particular focus of the project was the construction of suitable simultaneous confidence intervals. We also did work on multi-arm superiorty trials for phase III and Phase II.
