My research is situated at the intersection of prosody, second language (L2) acquisition, pedagogy, and machine learning. I am dedicated to discovering and describing new prosodic phenomena in world languages. For instance, one ongoing project involves detailing and analyzing the lexical tonal system of the Feixiang dialect, which is native to my hometown. Having served as a Mandarin instructor for many years, I am also keen on exploring how L2 Mandarin speakers acquire tones and intonation. Currently, my focus is on providing automatic, multifaceted feedback—visual, textual, and audio—that goes beyond mere scores of 'correct' or 'incorrect'.
