2001 – 2005: BSc Chemistry and Mathematics at the Hebrew University.
2005 - 2008: MSc (with honor).

BA - mathematics and chemistry, MSc (with honors) - applied chemistry (Supervisor Prof. Yoel Sasson), both at the Hebrew University of Jerusalem

research areas:

The theme of my master thesis was to study and develop a kinetic mechanism of Ru nanoparticles self-assembly  during chemical reaction. During the research I synthesized organometallic complexes and used different analytic characterization and computation methods. Finally I suggested new steps for a classic mechanism of nanoparticles bottom-up formation.

During PhD degree I assemble thin asymmetric films using Langmuir technique. These films are highly attractive in a modern membrane technology. The films comprise of a danse Langmuir layer from the hydrophobic nature attached to a hydrophilic porous backbone. In addition, I am trying to construct selective thin films both by LbL and SAM techniques. These films can be used either for sensing (of water pollutants, for example) or to produce molecular selective skin for separation membranes.

Post doctor

Academic History:

2000-2005: BSc in chemistry at Ben Gurion University.
BSc in chemical engineering at Ben Gurion University.
2006- 2013: PhD in Electrochemistry at the Hebrew University.

Research Areas: Developing new techniques to study and manipulate nanoparticle systems with scanning electrochemical microscopy (SECM).
SECM technique offers a very elegant way for experimenting with local chemistry and process analysis. New methods that combine electrochemistry with the SECM technique target the study of nanoparticle systems. Among the investigated processes are the local deposition of metals and semiconductors nanoparticles, and the local chemistry with nanoparticles on different types of surfaces such as conducting polymer films and semicoductors.This research pushes the limits of the SECM technique.
