Tatiana Nikitina works on linguistic representation of spatial relations and motion events. Her Topoi-based project focused on the diachronic development of motion expressions in Ancient Greek, and in particular, on the gradual spread of specialized expressions for goals of motion attested in the period from Homer to Classical Greek. This development has parallels in other branches of Indo-European and provides important evidence for changes in the representation of spatial relations from ancient to modern Indo-European languages.
