Post Doctoral Researcher
My research focus on the understanding of basic principal of the protein fold around metal ligands within Electron Transport proteins. This knowledge may lead to better understanding of the evolution of biological electron transport as well as helping to design minimal protein fold with electron transport properties.
I received B.A degree from Hebrew University in Biology and Marine Sciences. My combined M.Sc. and PhD thesis focused on the cyanobacteria inhabit the biological soil crusts (BSC). The research examined the mechanisms whereby cyanobacteria of the desert BSC cope with extreme environmental conditions using innovative field and laboratory techniques.. I received my PhD from Dept. of Plant and Environmental Sciences at the Hebrew University of Jerusalem, Israel, on June 2015.
