University of Illinois Urbana-Champaign


I’m currently a graduate student at the University of Illinois at Urbana-Champaign where I’m pursuing a doctorate in Informatics with a focus in Spatial Informatics. At UIUC I work as a research assistant under Dr. Shaowen Wang at the CyberInfrastructure & Geospatial Information Laboratory (CIGI) and CyberGIS Center for Advanced Digital and Spatial Studies. My work focuses on accessibility, meaning (1) using cyberGIS to explore, model, and analyze spatial patterns and systems of inaccessibility and inequity and (2) in making cyberGIS tools and technology accessible to all.

SPASTC: a Spatial Partitioning Algorithm for Scalable Travel-time Computation

We present a Spatial Partitioning Algorithm for Scalable Travel-time Computation (SPASTC) Calculating travel-time catchments over large spatial extents is computationally intensive, with previous work limiting their spatial extent to minimize computational burden or overcoming the computational burden with advanced cyberinfrastructure SPASTC is designed for domain decomposition of travel-time catchment calculations with a user-provided memory limit on computation SPASTC realizes this through spatial partitioning that preserves spatial ...
