Research Interests

The major interest of my research lies in the elucidation of the nociceptive circuit in the spinal dorsal horn. By studying the properties of synapting transmission I am trying to understand the changes that lead to increased network excitability that governs many pathological pain states. Additional research is focused on the properties of GABAA-receptors, GABAergic synaptic transmission and their role in neurological disorders.
