Current Project

The purpose of this project is to use nationally representative data and metropolitan statistical area (MSA) as the analytic unit to investigate the relationship among walkability, physical activity, food outlet density, expenditure of fast food, and trajectories of BMIs.


Illustrations of an ongoing project regarding sample selection process based on MSAs and density analysis of fast food restaurants. Model builder will be used for more in-depth analyses.

  • Sample Selection


  • Food Outlet


Rural Home Healthcare Need Analysis Project

This study was conducted to provide information for nonprofit organization in Harrison County in regards to home health care availability, gaps in service, and related needs for services. This is a project subject to the lifespan of all Harrison County residents that are homebound, have limited mobility, limited available transportation, and those living with high levels of medical care.


Selected figures showing results of geostatistics, network analysis on rural transportation services, and side-by-side simultaneous illustration of block groups and zip codes for project clients

  • Possible Home Health Needs


  • Transportation & Existing Services


  • Block Groups, Cities & Zip Codes


Obesity & Fast Food Restaurants Project

This project was S603 course final assignment. The main purpose was to investigate the distribution of the Fast Food restaurants and schools from a local entity (e.g., Bloomington/Monroe County) in Indiana to provide preliminary information for further research opportunities.
