I am an Assistant Professor in the Department of Geography at the University of Connecticut, USA. My research interests are focused on GIScience , community health, and transportation . I employ GIS instruments (e.g., big data analytics, geovisualization, deep learning) and accessibility theory to unveil the socioeconomic inequalities and health repercussions as results of the lack of health-promoting services and resources in communities. I also have research interests in location models, network analysis, 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
