Projects

Micro-Scale Transportation Network Modeling and Spatial Analysis for Three-Dimensional City

2008-current, Ongoing collaboration with Department of Geography & Earth Sciences, UNC-Charlotte. Humans spend a lot of their time indoors, and with the ever-increasing complexity of built environments in the three-dimensional city, there is a great need for developing navigation tools for negotiating indoor environments. A number of challenges arise, however, when attempting to model indoor micro-spaces and/or track human movements in these spaces. Still, it is clear that traditional, two-dimensional urban geography scholarship is no longer up to the task of representing cities as they actually exist—as three-dimensional spaces that feature numerous micro-scale spaces. To put it most simply, spatial relationships are captured best when they are represented in the same three dimensions that comprise the built geographic space. Our research reveals the viability of this approach for three explicit types of urban analytical functionalities: facility location planning, spatial accessibility assessment, and route planning.

Spatial Mobility and Momentary Ecological Assessment of Health

2013-current, Ongoing collaboration with UM Rural Institute: RTC Rural. With data that includes both EMA self-report on health conditions and GPS coordinates, we are able to utilize space-time path and space-time prism visualization techniques developed under Time Geography framework to capture the impact of individual activity sequencing under space-time and pain constraints.  Future research agenda includes studying spatial-temporal geography of pain, understanding health conditions as constraints to daily travel patterns and community participation, and developing geovisualization techniques.
