Itamar Willner is Professor of Chemistry at the Institute of Chemistry, The Hebrew University of Jerusalem, Israel. He graduated from the Hebrew University (1978), and after postdoctoral research at Berkley, he joined the faculty in Jerusalem in 1982. Prof. Willner is well known for his research in the areas of molecular electronics and optoelectronics, nanotechnology, bioelectronics, biosensors, optobioelectronics, nanobiotechnology, supramolecular chemistry, nanoscale chemistry and monolayer and thin-film assemblies. Prof. Willner holds the Israel Prize in Chemistry (2002), the Israel Chemical Society Award (2001) and the Max-Planck Research Award for International Cooperation (1998). He is a member of the Israel Academy of Sciences and Humanities and a member of the European Academy of Sciences. Eugenii Katz is a Senior Research Associate at the Institute of Chemistry, The Hebrew University of Jerusalem, Israel. He completed his Ph.D. in 1983 at the Frumkin Institute of Electrochemistry, Moscow, and until 1991 acted as senior scientist at the Institute of Photosynthesis, Pushchino, Russia. In 1991 he performed postdoctoral research at The Hebrew University of Jerusalem and later, as a recipient of the Humboldt scholarship, he worked at the Technical University of Munich (1993). He joined the research group of I. Willner at the Hebrew University in 1994. Dr. Katz holds the Kaye Awards for Scientific Innovations (1995 and 2004). His research interests include electroanalytical chemistry, functionalized monolayers, functionalized nanoparticles, biosensors, biofuel cells and bioelectronics.
