He received his PhD in Applied Physics in 1994 from the Hebrew University of Jerusalem, Israel. Dr. Palanker studies interactions of electric field with biological cells and tissues in a broad range of frequencies: from quasi-static to optical, and develops their diagnostic, therapeutic and prosthetic applications, primarily in ophthalmology. Several of his developments are in clinical practice world-wide: Pulsed Electron Avalanche Knife (PEAK PlasmaBladeTM), Patterned Scanning Laser Photocoagulator (PASCALTM), and 3-D Image-guided Laser System for Cataract Surgery (CatalysTM). In addition to laser-tissue interactions, retinal phototherapy and associated neural plasticity Dr. Palanker is working on electro-neural interfaces, including the Photovoltaic Retinal Prosthesis for restoring sight to the blind.
