Stefan Georg studied comparative linguistics and several Asian languages at the university of Bonn, where he earned his PhD in Central Asian Linguistics, Indo-European and Manchuristics. He specializes in the methodology of language comparison, questions of the ethnolinguistic history of Eurasia, and issues of historical and descriptive linguistics of this vast area, including the Mongolian, Turkic, Tungus, Indo-European, South-Caucasian and Tibeto-Burman language families. One of the focus areas of his research are the so-called Palaeoasiatic languages of North Asia/Siberia. After a description of the Thakali language (Tibeto-Burman/Nepal) and a grammar of Itelmen, the indigenous language of the Kamchatka peninsula (co-authored with A.P. Volodin, St. Petersburg), this Grammar of Ket is his third monograph devoted to the description of an endangered language. He currently works as a project manager in the translation industry.
