Yunjeong is a lecturer at Singapore University of Technology and Design (SUTD). She has obtained her PhD from National University of Singapore in 2026, where her research explored how programming languages and their tooling can be designed to better reflect user intent. Her work focuses on developing intuitive, example-driven techniques for constructing and repairing languages and their tooling, drawing on meta-programming, program synthesis, and automata-based methods.

Her research interests include programming languages, language tooling, and computing education, with a focus on intent-centred approaches to language design, example-driven methods for repairing languages and tools, and AI-assisted techniques for learning and teaching programming languages. More broadly, her work seeks to make language infrastructure more accessible, explainable, and aligned with human reasoning.

Prior to her doctoral studies, she worked as a consultant at Samjong KPMG in Korea, where she was involved in projects related to Industry 4.0 technologies. She received her MSc in Information Systems and Technology from the Skolkovo Institute of Science and Technology in 2017 and her BSc in Finance and Mathematics from New York University in 2013.
