Recent position:

senior research fellow

  Research Area

Invertebrate neurobiology, neurotoxicology, environmental toxikology; characterization of neurotoxic effects on aquatic invertebrate animals.

  Research Description

Toxic effects are described as alterations in neuronal activity controlling different forms of behavioural patterns, moreover, the neuromodulatory effects are analysed on a sigle neuronal level, as changes of neuronal communication and membrane functions. Finally, identification of the neuronal targets (membrane receptors, ion channels, etc.) and background mechanisms concerned using combination sof electrophysiological, morphological and pharmacological, as well as molecular techniques.
