Research Interests
Ion channels are macromolecular protein complexes which from pores across cell membranes to permit controlled movement of inorganic ions into and out of cells. The channel pores open and close in response to specific signals which link channel activity to various physiological functions including signal transmission between cells and metabolism. Voltage-gated sodium channels (NaV channels) are unique among the diverse family of ion channel proteins because they trigger action potentials - a basic feature of excitable cells and the basis for rapid electrical communication along and between neurons and myocytes. 

We use a combination of electrophysiological techniques (patch-clamp) and molecular biology methods to study the involvement of NaV channels in human diseases such as peripheral pain disorders and epilepsy. To better understand the disease mechanisms we investigate malfunctions of the channel proteins caused by mutations in the channel-encoding genes of affected patients and we analyze the impact of the mutations on the electrical properties of affected neurons. 
Furthermore, we study the interaction between the channel proteins and specific neurotoxins from venomous animals (e.g. marine cone snails, scorpions) because some neurotoxins are valuable tools for analyzing and understanding the basic principles of channel function.
