Ori Shachmon is a dialectologist, specializing in the documentation, description and analysis of spoken Arabic dialects. Her studies deal with the Arabic varieties currently heard in Israel, among which are many distinct Palestinian dialects and Jewish varieties of Arabic. 
Striving to observe the history of the Arabic language through the prism of its modern dialects, her studies also delve into the fascinating mosaic of peninsular Arabic, paying special attention to Yemen. Her monograph "Tēmōnit - The Jewish Varieties of Yemeni Arabic" was published in 2022 by Harrassowitz. 
At HUJI she regularly teaches a course on Palestinian Arabic, which serves as an introduction to the field of Arabic dialectology. In addition she offers varying elective courses, exposing the students to advanced grammatical topics in various dialects throughout the Arab world, or to issues in Arabic sociolinguistics. She also offers an applied workshop focusing on the methodology of linguistic fieldwork.
