Our Research (still) Goes to Work

Organizations and communities are facing difficult times right now. The challenges keep coming. It’s time to get creative. We believe we can look for solutions together.

While our facilities in Duluth and Coleraine are closed, NRRI researchers, along with our colleagues across the University of Minnesota, are working remotely. As an applied research institute, our mission is to deliver research solutions to balance our economy, resources and environment for resilient communities. There has never been a more critical time for us to deliver creative solutions to the challenges we are currently facing.

We believe we can help.

So we ask: What do you need?
