Phonology and phonetics of sonority-driven stress 
I've been working on the phonology and phonetics of metrical structure in Gujarati, with the goal of presenting acoustic evidence for (or against) sonority-driven stress. 

Default/focal prosodic phrasing 
I am also working on the default/focal prosodic phrasing in Taiwan Mandarin (syntactically) flat structure, with the goal of determining and formalizing the prosodic structure.

Interaction between phrase-final lengthening and prosodic structure 
I propose a unified theory for the interaction between phrase-final lengthening and prosodic structure. The theory makes a typology. I argue that phrase-final lengthening in Taiwan Mandarin provides evidence for the proposed theory.
