News

We are seeking excellent MSc., PhD, and Postdoc candidates

Additional Information

Areas Of Interest
  • Evolutionary insights into genome instability
  • Evolution of organelles and endosybiotic gene transfer

I am a senior Lecturer at the Department of Natural and Life Sciences, The Open University of Israel. I received my PhD under the supervision of Prof Dan Graur at Tel Aviv University studying molecular evolution. I then joined as an independent fellow to the National Evolutionary Synthesis Center at Durham, North Carolina, USA. Next, I joined the group of Prof. Thomas Petes at Duke University as a postdoc.
In my group we study questions in the areas of Genomics, Molecular Evolution and Bioinformatics. More specifically we are interested in Organelle evolution and in Signatures of Genome Instability.

Mitochondria and chloroplasts are descended from free-living bacteria. The endosymbiosis theory explains why organelle genomes are significantly smaller than that of proteobacteria and cyanobacteria. We study endosymbiotic gene transfer, specifically the current transfer of mitochondrial and plastid DNA fragments into eukaryotic nuclear genomes which giving rise to nuclear copies of mitochondrial DNA (numts) and nuclear copies of plastid DNA (nupts).

DNA damage response (DDR) is a mutagenic process that leaves signatures in DNA. We are interested in such signatures that occur through evolution and population genetics. Such signatures can teach us about the mutagenic process. Till now we have focused on signatures of non-homologous end joining (NHEJ) and on the affect of inverted repeats on genome instability
