Research on skeletal morphology focuses on change in the human skeleton in response to genetic drift, mutation, adaptation and interaction with the physical and biological environment. Craniometric and geometric morphometrics, as well as biochemical and molecular techniques are being used to study the biology and life history of skeletal populations from archaeological sites.
Physical anthropology of ancient populations
The skeleton, in particular, the cranium, limb bones and pelvis provide important evidence for reconstructing age, sex and stature of an individual. These are important life-history details that are relevant for understanding the physical, behavioural and cultural history of ancient populations. State-of-the-art techniques are being used to study these aspects of the skeleton from archaeological sites in the Republic of Georgia.

Paleopathology and paleoepidemiology
To determine environmental stress factors and document trends in population health in prehistoric populations we are studying hypoplasias – macroscopically observable lines on the outer enamel of teeth linked to events of stress or insult in an individual’s life. We are also looking at other chronic and infectious disease and oral pathogens in order to study how human health has changed over the last 5000 years.
Examples of trepanation, cribra orbital, enamel hypoplasia, porotic hyperostosis.
Intentional cranial modification
Intentional cranial deformation was practised in several parts of the world. We have several modified crania in our osteological collection and at the archaeological site in Georgia. We aim to use geometric morphometric techniques to study cranial shape modification in a comparative context in order to understand the behavioural practices of the people with modified crania and the cultural origins of the practice.

Reconstructing diet and migration patterns of ancient populations
Stable isotopes provide important signatures of past ecology and diet. This project focuses on analysing isotopes of carbon, nitrogen and strontium from the archaeological region of Mtskheta, Georgia, to trace the changing ecological landscape, diet, migratory pattern and human-faunal interaction from the Bronze Age to the Medieval Period.
Genetics of ancient populations
As part of an ongoing research project on the archaeology of the Caucasus we are studying the genetic diversity of ancient human populations from the Mtskheta region of Georgia. This will help understand familial relationships, migration and admixture patterns over a period of about 5000 years.
