I am a postdoctoral researcher at the Multilingual Phonetics Lab at Seoul National University. I recently earned my Ph.D. in Linguistics from the University of Wisconsin-Milwaukee. My research primarily focuses on how non-native speakers acquire and process second language (L2) speech, with a particular emphasis on psycholinguistic approaches. Currently, I investigate individual differences in L2 speech learning and processing, exploring the dynamic relationship between speech perception and production. Additionally, I am actively involved in developing an ultrasound corpus of non-native speakers at the Multilingual Phonetics Lab.
