 Jennifer Russell joined Virginia Tech’s “Curious Conversations” to talk about the concept of a circular economy. She explained that a circular economy is a shift away from the linear economy, which follows a take-make-dispose model, and instead focuses on reducing waste and reusing materials and shared examples of tangible products and industries that can be, or already are, part of a circular economy. 

About Russell

Russell is an assistant professor in the College of Natural Resources and Environment and a faculty affiliate of the Global Change Center in the Fralin Life Sciences Institute.

Stefan Duma joined Virginia Tech’s “Curious Conversations” to talk about the history of the Virginia Tech Helmet Lab and the impact it has had on sports-related head injuries. He shared how a military research conference led him to study helmets, as well as the critical role the lab’s relationships with the Virginia Tech football and sports medicine programs have played in advancing this pioneering research. Duma discussed the role of the helmet lab in helping to create a greater awareness about head injuries throughout all sports, and described the helmet shell add-on fans can witness during the football team’s spring game on April 13.

About Duma

Duma is a University Distinguished Professor and the Harry C. Wyatt Professor of Engineering in the Department of Biomedical Engineering and Mechanics. He is also the director of the Institute for Critical Technology and Applied Sciences and the founder of the Helmet Lab.
