My research revolves around the question how language is used in different discursive contexts and how these uses shape the structure of language. I study Semitic languages, specifically Classical Arabic, Egyptian Arabic, Palestinian Arabic, Modern Hebrew, and Neo Aramaic. The topics on which I conducted research include: tense-usage in different discourse environments, clause combining, presentatives, expressive structures, narrative structure, discourse markers, digital genre analysis, spoken and written discourse, and language contact (Arabic and Hebrew). My present research project, funded by the Israel Science Foundation, focuses on discourse markers in conversational and written Egyptian Arabic. In addition, I am a member of a network of interactional linguists studying responsive particles in conversation. Another field which I study is emergent practices in interactional digital discourse (e.g., in WhatsApp).
