My research interests lie in developing theories, methodologies, and applications for analyzing spatio-temporal dynamics of human and environmental phenomena by adopting statistics, data mining, and machine learning techniques.
I am currently involved in an interdisciplinary research project, MOASIS (Mobility, Activity and Social Interaction Study) as a postdoctoral researcher at the University Research Priority Program 'Dynamics of Healthy Aging' and the Department of Geography, University of Zurich.
My current research projects include but not limited to:
- Theories and Statistical Methodology Development for Measuring Spatial and Temporal Heterogeneity and Bursty Patterns of Geographic Events;
- Human Mobility Pattern Analysis using Multi-Sensor Datasets including GPS, Accelerometry, Audio data, and Momentary Survey Data;
- Automatic Place Detection and Semantic Trajectory Analysis using Machine Learning;
- Longitudinal and Spatial Analysis of Older Adults' Mental Health and their Socio-Environmental Status.
