Research Experience
Currently a Postdoctoral Associate at the Singapore-MIT Alliance for Research and Technology (SMART), working with Prof. Daniela Rus and Assoc. Prof. Bryan Kian Hsiang Low.
Education
Ph.D. in Data Science from the National University of Singapore (NUS), supervised by Assoc. Prof. Bryan Kian Hsiang Low, 2024; Bachelor of Science (Honors) in Data Science & Analytics and a minor in Computer Science from NUS, 2020. Ph.D. supported by the President’s Graduate Fellowship jointly offered by the NUS Graduate School Integrative Sciences and Engineering Programme (ISEP) and the Institute of Data Science (IDS), and the Singapore Data Science Consortium (SDSC) Dissertation Research Fellowship.
Background
Research interests include, but are not limited to: data-centric AI (e.g., data valuation & selection, collaborative machine learning, incentives, fairness), resource-efficient machine learning (e.g., Bayesian optimization), large language models (e.g., inference-time techniques, prompting), and deep learning & applications.
