Research Overview

 

GeoHealth Lab seeks to understand environmental health (particularly exposure to air pollution), environmental justice, and health disparities using GIS, geospatial technologies, and spatial statistical methods.

 

The core concept within this broad range of topics is human mobility. Noting that people move around over space and time, GeoHealth lab goes beyond residence-based static approaches and utilizes fine-grained spatiotemporal methods and travel pattern data (e.g., GPS tracking data, travel-activity diaries, and data collected from low-cost sensors) to untangle the complexities of the social/environmental impacts on health and health disparities. Incorporating human mobility into environmental health research is important because it enables the examination of a full spectrum of geographic and temporal contexts in which people interact with environmental/social factors.

 

 

Ongoing Research Projects

 

 

 

Ethics Protocol for Vaccine Distribution and Eastern North Carolina COVID-19 Mapping (2020)

 

• Sponsor: COVID-19 CARES Act Research Fund, North Carolina General Assembly.
• Project Objectives: 1) To enhance public health monitoring and surveillance capabilities of SARS-CoV-2 (COVID-19) in eastern N.C. through advanced geospatial analysis and visualization methods and 2) to identify high priority populations for vaccine distribution and delivery.  

 

A Low-Cost Mobile Air-Pollution Sensor with Geospatial Mapping: A Tool for Community-Engaged, Environmental Health Disparity Research (2020-2022)

 

• Sponsor: Center for Human Health and the Environment (CHHE) Pilot Project Grant, CHHE at North Carolina State University (supported in part by the National Institute of Environmental Health Sciences [NIEHS] under Award No. P30ES025128).
• Project Objectives: To test the feasibility of a user-friendly, portable, low-cost air-sensing device, coupled with geospatial mapping technologies, as a tool to engage environmental justice communities and promote community awareness of air pollution and health risks.

 

 

Community Air Quality Monitoring Using Low-Cost Air Sensors and Citizen Science Approaches (2020-2021)

 

• Sponsor: Engaged Outreach and Scholarship Academy (EOSA) Research Grant, Office of Community Engagement and Research, East Carolina University.
• Project Objectives: To engage communities to establish a dense air monitoring network using low-cost sensors in eastern North Carolina.

 

Mapping Accessibility with Dignity: An Inclusive, Equitable University Environment for People with Disabilities (2020-2021)

 

• Sponsor: Diversity and Inclusion Research and Scholarship Program Seed Grant, Office for Equity and Diversity, East Carolina University.
• Project Objectives: To create an interactive web map that supports the accessibility of individuals with disabilities using GIS to create a more inclusive, accessible campus
