Hi! I'm a fourth-year PhD Candidate in the Department of Linguistics at Stanford University, advised by Dan Jurafsky.
My research focuses on data-centric approaches to creating speech and language technologies for digitally-underserved languages and user populations.
In recent work, I have been examining how state-of-the-art models trained for major languages can be adapted for speech information retrieval applications related to endangered language documentation and revitalisation.
I am an Affiliate Member of the ARC Centre of Excellence for the Dynamics of Language (CoEDL) and a Visiting Fellow at the Australian National University (ANU), where I was based prior to Stanford and, where I developed tools and workflows to help clean, process, and transform lexicographical data from several Australian Aboriginal languages (Arabana, Kaytetye, Warlpiri, Warumungu).
I am also affiliated with Stanford SPARQ, where I am part of a research team examining how moderation algorithms and other users respond to reports of discrimination on Nextdoor.
I'm excited to spend Summer 2022 interning with the Siri and Language Technologies (SaLT) team at Apple to investigate data selection approaches for improving rare-word speech recognition.
To pay forward the benefits I received from tutoring as a young immigrant kid (lived in 8 countries by 21), I volunteer as a maths tutor in the East Bay with Refugee & Immigrant Transitions. If you are from a historically underrepresented group and are interested in speech and language technology research, feel very free to e-mail if you'd like a chat!
