Promoting Environmental Justice Populations’ Access to Opportunities within Suburban Boomtowns: An Interdisciplinary, Mixed-Methods Approach to Addressing Infrastructure Needs

Jandel Crutchfield Courtney Cronley , Kate Hyun
In the last twenty years, the population increased over 100% in Collin County, Texas. The county is projected to have over 2.4 million residents by 2050 -- more than three times its population in 2010.

E-Scooters and Public Health: Understanding the Implications of E-Scooters on Chronic Disease

Health implications other than injuries are likely, but there has been no investigation to date of e-scooter impacts on chronic disease. For example, there is some indication that e-scooters are replacing some auto trips with about a third of users self-reporting the trip would… Read More
