My research interests primarily lie in the study of the morphosyntactic structure of Tagalog, and the documentation and description of Philippine indigenous languages. Currently, I am working together with teachers from the Buhid Mangyan community in Oriental Mindoro to produce a dictionary and description of their language.

I also teach Chinese Mandarin at the UP Department of Linguistics. Doing so has also made me interested in investigating second language acquisition -- particularly how one's L1 and/or heritage language/s influence/s the learning of a second language.
