David Cahen

David Cahen is full professor (emer.) in the WIS Dept. of Materials & Interfaces and in the Bar Ilan Univ, BIU, Chem. Dept. and a member of BINA, Bar Ilan Centre for Nanotechniology and Advanced Materials. He runs the Zaban group since the latter's ascendency to the presidency of BIU  (as well as a group at the Weizmann Inst. of Science, WIS). Cahen studied chemistry & physics at Hebrew Univ. of Jerusalem (HUJ), materials science & physical chemistry at Northwestern Univ., and, as PD, biophysics of photosynthesis at the HUJ and the WIS. After joining the WIS faculty he specialized in optoelectronic materials chemistry & physics; today his research centers on fundamentals of materials for solar cells, and of electron transport across proteins, including implications for bio-optoelectronics. He is an AVS and MRS fellow.

Arie Zaban

Arie Zaban was born in Israel in 1961. He earned a B.Sc. in Chemistry (summa cum laude) and a Ph.D. in Electrochemistry (with highest distinction) at Bar-Ilan University (1987-1995). After a 2 year postdoctoral stint at the US National Renewable Energy Laboratory (Denver, CO), he was appointed to the senior faculty at Bar-Ilan (1998), where he is currently a Full Professor of Chemistry and Director of the Bar Ilan Institute for Nanotechnology and Advanced Materials.
