About Me

I am an Assistant Professor at Information Systems Technology and Design (ISTD), Singapore University of Technology and Design (SUTD), Singapore. I obtained my Ph.D. degree from the School of Computer Science and Engineering, Nanyang Technological University (NTU), Singapore in 2018. My supervisors are Prof. Zhang Jie and Dr. Xu Chi. My research topic is artificial intelligence, specializing in trustworthy recommender systems. 

I am leading the Trustworthy User Modelling and Personalization (TUMP) Lab at SUTD, mainly focusing on (1) applying data mining and machine learning techniques to design trustworthy (e.g., robust, diverse, fair, explainable, privacy-preserving) recommendation algorithms in various domains, such as e-commerce, location-based social networks (LBSNs), and healthcare; (2) benchmarking recommendations for fair comparison by leading the development of open-source libraries DaisyRec and DaisyRec-v2.0. 

Research Interests
