Students and Members


Alexander Kotlyar (PI.)

Alexander Kotlyar is currently a Professor of Biochemistry at Tel Aviv University. His fields of expertise are biochemistry, enzymology of soluble and membrane bound proteins, electron transfer in DNA and proteins, time resolved spectroscopy and DNA synthesis. His major research interests since 2001 focus around the DNA-based nanostructures. During the last 4 years he and members of his group at Tel Aviv University developed a novel methods of enzymatic synthesis of long (up to 10  thousand base pairs) uniform poly(dG)-poly(dC) double stranded DNA as well as triple- and quadruple-stranded (G4) DNA. He also developed novel methods for production of long nanostrucures based on 4G and triple-stranded DNA. In his research Dr. Kotlyar uses various experimental techniques, i.e. HPLC, UV/VIS absorption spectroscopy, fluorescent and CD spectroscopy and FRET analysis.
 Gennady Eidelshtein (PhD student)

Got his B.Sc degree in Biotechnology from Hadassah, Jerusalem, Israel, in 2009. In 2012 Gennady holds his Master's degree in Materials & Nanotechnology at Tel Aviv University under supervision of Prof. Alexander Kotlyar. Today Gennady is a Ph.D. student in Alexander Kotlyar group. His research is focused on novel metal and DNA-based functional nanomaterials.,d.d24
 Gabi Avishai (M.Sc student)

Studying towards M.Sc in Biochemistry, Gabi is working on targeted delivery of lipid and gold nanoparticles to cancer cells.,d.d24
 Roy Cohen (M.Sc student)

After receiving his bachelor’s degree in life sciences, Roy turned to biochemistry due to keen interest in Alexander’s work. Currently, Roy is studying the mechanism of Prokaryotic DNA Polymerase I, and the effects of different substrates on its activity. 

 Benjamin Kempinski (M.Sc student)

Research interest revolves around synthetic metal-nano-particles and their interactions with various forms & structures of DNA.
 Liat Katrivas (M.Sc student)

Got her B.Sc in Life Sciences from Tel Aviv University
The main goal of her research is to develop new method for long linear DNA polymerization using ligation.
Such development will later provide the basis for fabrication of DNA-based conducting wires  and other clinical opportunities.
