Research Fellow (Artificial Intelligence), The University of Auckland.
Expert panelist on AI and healthcare with the Office of the Prime Minister’s Chief Science Advisor, New Zealand.
I am a Research Fellow at the School of Computer Science, University of Auckland. My current research focuses on bias in language models and developing an understanding of the area. This research has provided me with the backbone of knowledge in limitations, especially with the bias-related research impact on the NZ population. I have several publications on tackling bias in high-impact venues such as IJCAI and ICLR. I have extensive experience working on multi-disciplinary projects with academic and community impact in artificial intelligence and healthcare. I gained my PhD in domain-specific language models for multi-label classification of medical text at the University of Waikato under the supervision of Professor Bernhard Pfahringer. I then worked as a Post-Doc under the mentorship of Prof Michael Witbrock (Oct 2021-Dec 2022) in AI. Since January 2023, I have been working under the mentorship of Prof Gill Dobbie on tackling bias in large language models.
Throughout my PhD and post-PhD, I have published several papers at the intersection of AI and healthcare, including those that directly impacted NZ society. I have also won best-paper awards for such publications. I am also interested in researching the preservation of low-resource languages in the era of technology. My research outputs published in CORE-ranking A conferences, NAACL and AACL-IJCNLP, use deep learning models for language detection and code-switching in bilingual settings, including English-Māori language pairs.
Additionally, I have almost a decade of experience working in the NZ healthcare sector and several years of teaching tertiary students in NZ.
I am also a selected expert panellist on AI and healthcare with the Office of the Prime Minister’s Chief Science Advisor.
