Owen Rambow is interested in morphology, syntax (mainly), and semantics.  He is interested in linguistic analyses,  in formalisms that can be used to describe them, and in processing models. Much of his work (including his thesis on German syntax) is presented in the framework of Tree Adjoining Grammar (TAG), or at least is heavily influenced by TAG. One of the many interesting properties of TAG is that it bridges phrase structure and dependency representations of syntax. Owen has worked on both natural language generation and natural language understanding. Owen is also interested in how language is used in context, for example in email conversations or on Twitter. He has worked on how discourse participants signal beliefs and sentiments. He has also worked on how power and gender affect communication in written conversations. Owen has worked on many different languages, including Arabic, English, German, and Hindi.
