Our History:

The VGI-Lab at University of Nebraska-Lincoln (UNL) was initiated from two research projects funded by Nebraska Environmental Trust in 2011 and Nebraska Department of Environmental Quality in 2012. The lab is further developed from two EPA-funded projects in order to create mobile applications for citizen engagement in grassroots environmental efforts.

Our website has been funded wholly or partially by the United States Environmental Protection Agency (EPA) under an assistance agreement.
