[1][2][3] Throughout his career, Gachechiladze has held several positions, including the head of the Master Program "Demography and Population Geography" at Tbilisi State University, where he has also been a guiding force for numerous students and researchers.

[8][9] One of Gachechiladze's notable contributions to the field is his analysis of the emergence of the Newly Independent States at the end of 1991, a pivotal moment that marked the dissolution of the Soviet Union and the reconfiguration of geopolitical boundaries in the region.

His analysis of the pluses and minuses of development factors provides an understanding of the socio-economic transformations that have taken place in Georgia, offering a comprehensive overview of the country's journey towards modernization and integration into the global community.

[5] Another significant area of Gachechiladze's research revolves around the history of Georgian medieval and modern historiography, ethnic processes during Tsarist and Soviet periods, and the role of historical discourse and memory politics in regional conflicts in Georgia.

His work in this domain explores the ways in which historical narratives and collective memories shape contemporary geopolitical and social dynamics, offering insights into the interplay between history, identity, and politics in the Caucasus.
