I am an Assistant Professor with the Department of Computing and Decision Sciences at Lingnan University. Previously, I was with the Department of Computing at the Hong Kong Polytechnic University as a Research Assistant Professor from 2020 to 2022. I obtained the B.E. degree in Software Engineering from Jilin University in 2014, and the Ph.D. degree in Computing from the Hong Kong Polytechnic University in 2019. In 2017, I was a visiting scholar with the Media Lab at Massachusetts Institute of Technology.

The theme of my research is Human Dynamics which aims to understand human behavior and provide actionable insights via cross-disciplinary approaches. Under the theme, my research interests include Context Sensing, IoT Systems, Mobile Computing, and Data Mining. I have published over NA papers including top-tier journals and conferences such as IEEE TMC, IEEE TKDE, IEEE TPDS, ACM TOIS, ACM IMWUT, IEEE INFOCOM, and WWW (including NA CCF-A and NA CCF-B). I have also won two Best Paper awards including one from IEEE INFOCOM 2020.

Data-Driven Analytics of Human Dynamics

Below shows a pyramid of Human Dynamics research. It covers both my previous research effort and future directions.

Economic Level Human Dynamics
Social Level Human Dynamics
Psychological Level Human Dynamics
Physical Level Human Dynamics

Unknown and dark levels to be explored and lighted by us...

Economic level studies high-level human behaviors (e.g., decision-making, human bias) and profound social issues in significant sections like health, education, safety.

Social level refers to interplay between individuals including social tie, social influence, and social recommendation. Although social level is also difficult to capture and quantify, it is still feasible by combining physical and psychological cues.

Psychological level refers to mental things like emotion, personality, and cognition. This level is usually hard to measure directly and thus rely on measurements from physical level.

Physical level refers to human dynamics that can be directly observed. This level largely cares about low-level physical status (e.g., individuals' locations), activities (e.g., shopping, eating, and gestures), properties (e.g., gender).
