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

The theme of my research is Human Dynamics which refers to interdisciplinary research studying human behavior and providing actionable insights. Under the theme, I have several research interests including Context Sensing, IoT Systems, Mobile Computing, and Data Mining. I have published over 25 papers in top-tier journals and conferences like TMC, TKDE, TOIS, IoT-J, INFOCOM, WWW, ICDM, and ICDCS (including 7 CCF-A, 4 CCF-B, and 12 JCR-Q1). I have also won Best Paper twice including one from 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 you and me...

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).
