I am an Assistant Professor in the Department of Geography at the University of Connecticut, USA. My research interests are focused on GIScience and community health. I employ GIS instruments (e.g., space-time modeling, geovisualization, big data analytics) and accessibility theory to unveil the socioeconomic inequalities and health repercussions as results of the lack of affordable, healthy food access in communities. My secondary research interests include disaster response and remote sensing.

Remote Sensing

Simulation Toolkit for Mixed Pixel Phenology

  • The green-up date (GUD) characterizes the onset of measurable photosynthetic activities or the timing of spring arrivals.
  • Vegetation index products may contain mixed pixels, introducing uncertainties to GUD detection.
  • This simulation toolkit identifies the GUD in a mixed pixel based on the NDVI time series of the endmembers in the pixel.

Emergency Management

Network-based Evacuation Risk Assessment

  • In emergencies, evacuation via road networks is characterized with a high degree of uncertainties
  • The critical cluster model (CCM) is developed to quantify the evacuation risk in network-based neighborhoods
  • This custom simulation toolkit identifies the network vulnerability based on the CCM
