I was a Russian language teacher (but I am a native speaker of Korean) before I went to the University of Iowa to study Second Language Acquisition. My research focuses on learnability problems within the framework of generative linguistics, or the theory of Universal Grammar. I am interested in how expressions of definiteness are interpreted and acquired in a second language. I am currently working on a multidirectional study (English-Russian-Korean) on the acquisition of definiteness. I would like to work with students who are interested in investigating second language acquisition of syntax and semantics using psycholinguistic methodologies. I teach courses in second language acquisition, first language acquisition, and syntax.
