In this episode, UREx postdoctoral researcher, Sam Markolf, interviews Dr. Dan Eisenberg about resilience from an engineering perspective. When is being more robust the solution? When is flexibility preferred? Dan shares stories to illustrate when it may be advantageous to abandon standards of practice, how to deal with different types of surprises, and the differences between robust design and extensible design. They discuss the importance of designing infrastructure with human-technological interactions in mind. If you have questions, comments, or suggestions for future episodes, e-mail us at futurecitiespodcast@gmail.com or find us on Twitter @FutureCitiesPod.
