The main research interest of our group is the investigation of structural and functional (re)organization of cortical networks in health and disease.

The scaffold of proper structural and functional organization of the neuronal networks depends on the activity of a multitude of different transcription factors, growth factors and neuromodulators during brain development. 

Many neurological disorders and their related cortical dysfunctions can be linked with abnormal activity of one or more factors or neuromodulators - be it because of genetic variations or because of pharmacological modulation during critical periods of brain development. 

In our group, we are currently focussing on the structural and functional organization and maturation of excitatory (glutamatergic) and inhibitory (GABAergic) neural networks  with the four translational links: 

  • The role of the neuromodulator serotonin and stress on the development of excitatory/inhibitory circuitry in the rodent brain. 
  • Epigenetic factors and neuronal network formation in models systems (rodent & human) for intellectual disability and schizophrenia.
  • mTORopathies and deregulated GABA signaling in developmental epilepsy.

For our research we combine genetic editing (CRISPR/Cas), molecular, neuroanatomical, electrophysiological in vitro techniques (from single cell patch clamp over paired recordings to multielectrode array recordings), with optical stimulation (optogenetics), modelling as well as behavioural approaches, partially via intense collaborations with other research groups. 

To this end in our group we have a particular focus on using human induced pluripotent stem cell (hIPSC) derived neuronal networks.c
