Head of Physical Chemistry Application & Radiation Safety Officer

• Jan 2019 - Present

Postdoctoral Researcher

• Apr 2018 - Jan 2019

Chemistry Ph.D. candidate and teaching assistant

• Oct 2013 - Apr 2018

• Developed novel methods for surface modification of inorganic nanostructures.• Worked for a short time on carbon nanotubes functionalization project.• Characterized nanocomposites by SEM, TEM, DLS, ζ-potential, TGA, and more.• Used Minitab® Design-of-Experiment software for process optimization.• Operated an EFI Tecnai transmittance electron microscope.• Published three papers in which I have worked independently on most of the experimental work and characterization, and almost entirely on the literature review, writing and editing parts. In additions, I assisted my group members in writing and editing paper and theses. • Teaching assistant for general chemistry and organic chemistry students’ labs, in Hebrew and in English – for the foreign students Pre-Med program. The role included frontal instruction of the theoretical background, preparation of lab reports and quizzes, and guiding the students through the basics of lab techniques in practice: extraction, distillation, chromatography, synthesis and workup, analysis, documentation and results interpretation.

R&D Chemist

• Jun 2009 - Jan 2013

• Member of the lead team for establishing Israeli and US R&D laboratories for Virdia. • Provided analytical support for the US process pilot unit during the 2011 and 2012 campaigns, working closely with the engineering team to develop a solid base for the lab-operation handshake in the pilot unit. • Designed and performed process-related hydrolysis, extraction, impurities, lignin and other experiments through the development and dynamic changes of the process. • Used experimental techniques such as distillations (plain, vacuum, azeotropic), extractions, building equilibrium curves, reflux, pressure reactions, small-scale sugar refining, etc. • Participated in development and validation of analytical methods: HPLC, GC, titrations, spectroscopic and more. Familiar with the team's analytical analyses from the sample preparation stage to data processing. • Developed and validated a unique analytical method for rapid evaluation of critical process parameters using the DSA-5000 density and sound velocity meter. • Trained Israeli and US R&D teams and US pilot operation team in the above method. • Participated in designing LIMS software features for the lab and operation interfaces. Trained US R&D team and US pilot operation team in LIMS. Provided support to LIMS. • Wrote multiple SOP documents and user guides, for example: DSA-5000 operation, titration procedures, HPLC procedures, etc. Show less
