I received my M.A. in TESOL from Teachers College, Columbia University and my Ph.D. in Linguistics from the University of Illinois at Urbana-Champaign. I currently work as Professor of Applied Linguistics in the Department of English at National Taipei University of Technology. I am an experimental phonetician with a focus on phonetic and sociophonetic variations in speech production and perception, as well as second language speech learning/training. A notable aspect of my research has concentrated on the articulation, acoustics, and perception of Mandarin coronal (alveolar, retroflex, and palatal) consonants. 

My current research project, funded by Taiwan’s National Science and Technology Council (NSTC) for 2026–2027, investigates acoustic and articulatory variation in the production of the velar fricative /x/ in Taiwan Mandarin. I am also a co-PI on an NSTC-funded project investigating the effects of aging and cognitive decline on speech production (PI: Dr. Wen-hui Sah, Department of English, National Chengchi University).
