Episode 147: Living with uncertainty - using near-surface in urban settings

Yunyue Elita Li discusses her upcoming South & East Asia Honorary Lecture, "Listening to Singapore: Harvesting urban noise for space, water, and hazard mitigation." Elita shares how she designed novel signal processing techniques that turn urban hum into rich information about the urban system, both above and below the surface. She also outlines what public officials, citizens, and engineers should understand about geophysics to support sustainable practices and growth in urban environments. This episode is full of communication tips and scientific insights to improve life in our cities.
