Greetings! I am a fourth-year PhD candidate at the Faculty of Business and Economics, the University of Hong Kong. Previously, I earned my master’s degree at the Institute of Information Engineering, Chinese Academy of Sciences. I also served as a visiting scholar at the Alfred Lerner College of Business & Economics, University of Delaware.
My research interests focus on computational design science in information systems, encompassing areas such as generative AI, large language models, fair machine learning, data mining, and big data in business analytics. In this vein, I employ methods from both information systems and computer science to tackle real-world problems in business and society.
