Dr. Amy Mueller and her team are measuring the vital signs of cities, gathering data that will inform future additions and improvements to our urban areas. How do we build cities in a sensible, sustainable way? Key to this work is getting communities involved and arming them with the information they need to make strategic decisions about the future. Dr Mueller is an associate professor of marine and environmental science and civil and environmental engineering at Northeastern University in Boston. She spoke at a "Town Talk" sponsored by Telluride Science and the session was moderated by veteran broadcast journalists Judy Muller and George Lewis.
