Estara Arrant (PhD, University of Cambridge) is a linguist of Semitic languages, a scholar of medieval Jewish and Islamic textual history and culture, and a data and computer scientist and software developer. She was a postdoctoral research associate at the Genizah Research Unit on the ERC-funded project TEXTEVOLVE: A New Approach to the Evolution of Texts Based on the Manuscripts of the Targums. Her role in this project was to adapt bioinformatics algorithms used in evolutionary biology to analyse the textual evolution of medieval Targum manuscripts from the Cairo Genizah, Europe, and the Middle East, as well as to create new digital tools to assist in the analysis of large, complex textual data from the Targum text traditions. She is currently the University Library’s inaugural Leverhulme Early Career Research Fellow (January 2025–December 2027). Dr Arrant’s main research interest lies in creating innovative data/computer science and applied mathematical approaches to help address longstanding questions in our knowledge of Jewish and Islamic languages and cultures. She works also on the linguistics, philology, and codicology of everyday engagement with scriptures in the Geniza, and has an active interest in the evolution of the Hebrew Bible, Qurʾān, Arabic and Aramaic Bible translations, Tafsīr and Midrash. Recent publications include ‘An Exploratory Typology of Near-Model and Non-Standard Tiberian Torah Manuscripts from the Cairo Genizah’, in Studies in Semitic Vocalisation and Reading Traditions (University of Cambridge Faculty of Asian and Middle Eastern Studies and Open Book Publishers, 2020), and ‘A Further Analysis of the “Byzantine (Italian-Levantine) Triad” of Features in Common Torah Codices’, in Studies in the Masoretic Tradition of the Hebrew Bible (University of Cambridge Faculty of Asian and Middle Eastern Studies and Open Book Publishers, 2022).
