In this episode of Research Matters, we speak with Sriramya Duddukuri Nair, assistant professor of civil and environmental engineering in the Cornell Duffield College of Engineering, about the enormous — and often invisible — impact of construction materials on our climate and daily lives. From reimagining “green concrete” to experimenting with 3D-printed buildings made from local, in-situ materials, Nair explains how engineers are working to build faster, cleaner and more resilient infrastructure for a warming world. It’s a wide-ranging conversation about innovation under pressure — and why the future of climate solutions may be hiding in the concrete beneath our feet. Watch here.
