Research Summary:

My research focusses on understanding the complex regulatory networks underlying behavioural plasticity. Lasting behavioural changes – e.g. following long-term memory formation – involve fluctuations in gene expression, which need to be tightly regulated. Gene expression is regulated by a variety of mechanisms including epigenetic mechanisms (e.g. DNA methylation, histone modifications), non-coding RNAs and transcription factors. All these mechanisms interact and influence each other creating networks regulating gene expression in a temporally and mechanistically complex manner. To investigate the impact of regulatory mechanisms on behaviour I use the honey bee (Apis mellifera) and the fruit fly (Drosophila melanogaster).
