Research Project

The reproducibility crisis is questioning the credibility of scientific results. A cause, rather than a cure for poor reproducibility of experimental findings, could be the high standardisation to homogenous experimental conditions. The results are limited to the specific experimental background in which the experiment is conducted. This is assumed to decrease the external validity and to lead to poor reproducibility across experiments and laboratories. Instead, introducing variation into a single experiment in a systematic and controlled way, referred to as systematic heterogenisation, may reflect the inevitably occurring variation between experiments and laboratories and thus improve reproducibility.
My research interest focuses on the identification and validation of a practicable and feasible heterogenisation strategy to improve the reproducibility of research findings in behavioural phenotyping studies. (DFG, RI 2488/3-1)
