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 urban studies . I employ GIS instruments (e.g., big data analytics, geovisualization, deep learning) to to unveil the socioeconomic and health inequalities across urban communities.

My topical area is food access, evaluating if community members have equitable access to healthy, affordable food provisioning. I also have research interests in transportation studies, such as accessibility, location models, and network analysis.

COVID-19 RESEARCH

During the COVID-19 pandemic, I was heavily involved in related public health research and services.

Case Modeling

We propose an epidemic model to simulate COVID-19 infection on the town level. The model predicts cases of infection in every Connecticut town under different social distancing scenarios.

Web Mapping

Our department develops a COVID-19 web map product at the town level for Connecticut: covidct.org.

Health Inequity

We employ primary survey data and secondary health data to examine inequity issues arising from the pandemic, including vaccination and food access.

Tourism

We examine the impact of the coronavirus outbreak on tourism using econometric models and big data (e.g., mobile phone data, transaction data). These studies suggest policy initiatives to boost the tourist economy.

Mosquito Population Modeling

  • We have developed the mechanistic population model of Ae. albopictus (Asian Tiger Mosquito) with diapause (MPAD).
  • The model derives the mosquito population abundance in a seven-stage climate-driven development.
  • The original model (2016) is further extended to studying global warming (2017) and heat waves (2019).

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.

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
