The aim of my PhD project at the University of Cologne, Department of Byzantine Studies is a critical text edition supplied with philological, historical and linguistic commentary of the anonymous fragments of an early Byzantine historiographer (the so-called Anonymus post Dionem, commonly identified with Peter Patrikios). The fragments come down in form of the excerpts in the Collection of historical Excerpts of Constantine VII Porphyrogennetos (905-959). The fragments themselves are all contained in a single manuscript Vaticanus Graecus 73 - a palimpsest in a poor condition nowadays. Despite this fact I was able to precisely reconstruct the lower text as well as to prepare a preliminary version of a digital edition (a brief description of the digital edition see here; a description of the PhD project in German see here).

Apart from working on my PhD project and raising four children, from 2019 I am enrolled in a two-years' course in software development (IT-specialist, Chamber of Industry and Commerce of Germany qualification, to be obtained in January 2021).

Digital Humanities and Byzantine Studies

I am particularly interested in digital approaches into the study of the Byzantine Culture and History: statistics, visualisation, text presentation and analysis technics, digital scholarly editions, corpus linguistics, network analysis etc.

My ideal goal is to gain new insights into Ancient Greek language of the Classical und Byzantine periods, as well as into Byzantine culture and history, combining new digital approaches and traditional methodologies in the field.
