Andres is a postdoctoral fellow at the Growth Lab. He is currently investigating the mechanisms that explain the economic differences between cities in terms of their internal occupational and industrial mix. He is also helping with the development of atlases of economic complexity for Colombia, Mexico, and Peru. Since his doctoral studies, he has been part of the Cities, Scaling and Sustainability research group at the Santa Fe Institute. There, he has been investigating the statistical properties of urban aggregate output to extract information about how cities coordinate heterogeneous and interdependent individuals in large scale production processes. He holds a Ph.D. in Applied Mathematics from Arizona State University, a Master's degree in Industrial Engineering and a B.S. in Physics, both from La Universidad de los Andes in Bogota, Colombia.
