Research Topics
A Data-Driven Approach to Place-Based GIS
A place is characterized by its semantics and human conceptualizations instead of just an abstract geometry in space. The emergence of big data brings new opportunities for us to understand the semantics of places and associated human experiences, emotions, movements, and activities.

Social Sensing
The emergence of big data brings new opportunities for us to understand our socioeconomic environments. We use the term social sensing for such individual-level big geospatial data and the associated analysis methods.

Spatiotemporal Data Analytics
Spatiotemporal analytics, computation, mining, and integration with visual representation help understand complex phenomena and reveal hidden patterns.

GeoComputation and Big Data
Geospatial Big Data describes the phenomenon that large volumes of georeferenced data captured by millions of environmental and human sensors in a variety of formats such as remote sensing images, crowdsourced maps, geotagged videos and photos, transportation smart card transactions, mobile phone data, location-based social media content, and GPS trajectories.

Human Mobility and Urban Computing
The widespread use of location‐awareness technologies and smart phones has made it possible to collect large scale spatiotemporal data for analyzing human mobility patterns and complex urban dynamics.

Spatial Networks and Transportation
A spatial network is a graph in which the vertices or edges are spatial elements associated with geometric objects. It plays a very important role in transportation operation and management and many other fields.

Location Big Data for Business Analytics
Location information is a key component in business intelligence analytics (e.g., foot-traffic and trade areas) and implementation of crucial, revenue‐generating marketing strategies, such as location‐based advertisement and services.

Place Emotion
State-of-the-art computer vision technologies are utilized to collect, store, handle, manipulate and analyze the human emotion at different places. The research explored what and how people express their emotions at different scales and places, and why and how their emotions would be influenced by environmental factors.

Location Privacy
Large-scale individual-level location data has been widely collected through location-awareness devices. Geoprivacy concerns arise on the issues of user identity de-anonymization and sensitive location exposure. Advanced methods and techniques for protecting the geoprivacy are required.
