In March 2020, Prof. Pablo Hernandez-Lagos (Investigator) presented some of the CITIES research at the Urban Research Day, organized by the NYU Wagner Urban Initiative. He showed unique evidence on how Artificial Intelligence (AI) frontier knowledge is created across cities in the world. Beijing is by far the most productive. It is also the most cited city on the planet. However, Berkeley, Stanford, and Redmond WA (Microsoft’s headquarters) still engender the most disruptive AI research. The study casts light on the cities that are poised to be the next AI knowledge powerhouses.
