ACADEMIC APPOINTMENTS

2001-present   Full Professor, Tel Aviv University.  

1997-2001       Associate Professor, Tel Aviv University.

1992-1997       Senior Lecturer, Tel Aviv University.

1987-1992       Research Associate, Tel Aviv University.

1)      Study of the novel role of Kv2.1 potassium channel in insulin secretion from pancreatic islet β cells, as a target for novel drug design for the treatment of type-2 diabetes.

2)      Study of structure-function and modulations by presynaptic modulators of Kv2.1 and other Kv channels, specifically KCNQ2 and KCNQ3, important in axonal and synaptic excitability.

3)      Investigating the conformational changes of Syntaxin 1A during exocytosis, using novel fluorescent probes, and their implications exocytosis-related events, in general, and for Kv2.1-induced facilitation of exocytosis.
