Abstract: Mobility and activity levels are important indicators for healthy aging and continued research is needed to determine how older adult health can be maintained in urban settings. To assess individual mobility and activity, portable sensors such as global positioning systems (GPS) as well as ecological momentary assessments using surveys on smartphones are being used with increasing spatial and temporal resolution of data. This has enabled advanced studies on individuals’ real-life behaviors, health status, and psychological states at a micro spatiotemporal scale. In this talk, a series of studies will be presented including: (1) semantically enriched trajectory data construction from multi-modal data of sensors and momentary survey, (2) mobility indicator computation, and (3) within-person and between-person relations between individual characteristics, mobility, and wellbeing. The challenges and future directions will also be discussed.

Speaker Biography: Eun-Kyeong Kim is a geographer and spatial data scientist and is passionate to contribute to data science for understanding spatio-temporal processes of human behaviors, health, and environments. Her interest lies in multi-sensor trajectory data analytics for human mobility and health research as well as spatio-temporal statistics and data mining methods. She is currently a postdoctoral researcher in the Department of Geography, University of Zurich (UZH). Before joining UZH, she conducted her doctoral research at the GeoVISTA center, Penn State University in the United States.
