Sumikazu Yoda is an Associate Professor at the Graduate School of Humanities, Osaka University. He earned both his Bachelor of Arts and Master of Arts degrees from Osaka University of Foreign Studies, followed by a Doctor of Philosophy from the Hebrew University. Prof. Yoda's scholarly contributions are significant in the field of Arabic dialectology. His seminal work, "The Arabic Dialect of the Jews of Tripoli (Libya): Grammar, Text and Glossary," published in 2005, offers a grammatical analysis of this specific dialect. In 2006, he authored the article "‘Sifflant’ and ‘chuintant’ in the Arabic dialect of the Jews of Gabes (south Tunisia)," which appeared in the Zeitschrift für Arabische Linguistik, providing insights into phonetic features of the Gabes dialect. His 2009 study, "The vowel system of Cantilena: Its historical development," was included in the volume "Introducing Maltese Linguistics," edited by B. Comrie and others, and examines the evolution of vowel systems in Maltese. More recently, in 2019, the scholar published "Texts from Mahdiya (Tunisia)" in the Journal of Arabic and Islamic Studies, contributing valuable primary sources for linguistic analysis. Professor Yoda's research interests encompass Arabic dialectology, with a focus on Maghribi dialects, Arabic dialects of Jewish communities, modern Judeo-Arabic, and the Maltese language.
