The main focus of my work is on the influence of monoaminergic neurotransmitters like serotonin (5HT) and dopamine (DA) in relation to psychiatric diseases.
Currently in Trevor Sharp’s group, I am investigating electrical signals of 5HT neurons and cortical interneurons in the normal brain and during pharmacological inhibition of 5HT receptors in combination with neuroanatomical techniques.
Prior to this, I investigated how d-amino acid oxidase (DAO) influences midbrain DA physiology using electrophysiology, microdialysis and HPLC.
In Mark Ungless’s lab at Imperial College, I studied the functional diversity of dorsal raphe 5HT neurons using electrophysiology.
For my PhD with Wolfgang Hauber (University of Stuttgart), I investigated the involvement of the DA innervation of the anterior cingulate cortex on decision-making and learning. I have graduated from the University of Tübingen with an MSc in animal physiology, where I studied the role of the BNST on fear and anxiety behaviour with M. Fendt.
