Biography :


graduated from Tbilisi State University (Biology, zoology) (1982). PhD in Ecology from Research Inst. of Ecology, Ural Sci. Center at Sverdlovsk (pres. Ekaterinsburg), Russia, 1987. Research – interspecific competition of amphibians. Work experience – Tbilisi State University, Vietnam Tropical Center (1990), Bangor University, UK (1996-1997, post-doctoral fellow), Zoological Research Institute and Museum Al. Koenig, Bonn, Germany (1998; 1999-2003; post-doctoral fellow, researcher).Studies mostly in ecology, biogeography, population genetics and evolution of amphibians and reptiles. Over 100 published research papers. At Ilia State since 2006, employed as a dean of the school of Life Sciences, director of the Institute of Ecology, and dean of the School of Science and Engineering.

Research interests


  • Evolutionary biology
  • Speciation
  • Population ecology and genetics
  • Ecological modeling
  • Biogeography
  • Human population genetics
  • Caucasus
  • Amphibians and reptiles were the main research object for many years, however, in recent years the projects are on different organisms, including conifer plants, lizards, snails, domestic animals, and humans.
