Profile

I joined the Information School as a Lecturer in Data Science in September 2022. Before coming to 91̽��, I worked as a Postdoc researcher on the project “Data Management for Indoor Location-based Services (LBS)” at Roskilde University, Denmark, from October 2020 to August 2022. I obtained my PhD degree in Computer Science and Engineering from The Hong Kong University of Science and Technology, Hong Kong.

University responsibilities

Interim Deputy Programme Coordinator, BSc Data Science (Semester 2, 2023 - 2024)
Department Employability Lead for Data Science (2022 - )

Research interests

My research interests include data mining and analytics, data science, and big data. My research concerns foundations for efficient information retrieval, data management and knowledge discovery from different types of data such as spatial data, spatio-textual data, and spatio-temporal data. In particular, I worked on the problems of query processing on spatio-textual data, spatial co-location pattern mining, and in the area of indoor location-based services (LBS). I am also interested in applying machine learning models in databases to improve the quality and query efficiency of spatial data.

I am interested in supervising PhD students in the following areas:

Data mining and analytics for big data
AI for databases
Spatial data management
