Along with my collaborators, we presented a startup initiative at the Oxford University Urban Innovation Forum. The TimeLayers initiative was aimed at creating a platform for the visualization of urban data, with the goal of overlaying historic pictures to current urban landscapes. This project was part of the Public Entrepreneurship Laboratory at the School of Government and Public Transformation of the Tecnológico de Monterrey. The talk was given in English.
