I am a 2-year Ph.D. student in the School of Computing and Data Science (HKUCDS) at the University of Hong Kong (HKU), where I am fortunate to be advised by Prof. Reynold Cheng. My research lies at the intersection of Data Management, Graph Analytics and Approximate Statistical Inference, with a broader interest in tackling interdisciplinary database problems. I actively collaborate with renowned researchers, including Prof. Sihem Amer-Yahia (CNRS) and Prof. Laks V.S. Lakshmanan (UBC). I am always open to exploring new research ideas and collaborations, so feel free to reach out via email if you're interested in working together.
I hold a 1st class honors B.Sc. degree in Mathematics and Decision Analytics from HKU. My undergraduate thesis was supervised by Dr. Adela Lau from HKUCDS, where I developed a strong foundation in CNN and its downstream applications in crop price forecasting. Beyond academia, I expanded my research horizons through the 2022 RIPS Program at NUS IMS, where I collaborated with Grab on fraud detection using GNNs. These experiences have shaped my passion for leveraging data-driven methodologies to solve complex challenges.
