Research Area:

Cell physiology, structure activity relationships of drugs and receptors

Research Interests:

We are interested in developing new, boron based drugs that target nerve cells. Our focus is on ion channels and ligand receptors located in the neuronal plasma membrane. We express these proteins in heterologous cells and study them functionally using techniques of cell physiology such as whole cell voltage clamp. Our goal is to develop pharmaceuticals that have distinct advantages over existing drugs affecting the central and peripheral nervous systems.
