I am an assistant professor in the Management of Complex Systems Department and the Ernest and Julio Gallo Management Program at the University of California Merced. Before joining UC Merced, I was at the IMT Institute for Advance Studies Lucca (Italy), and prior to that, I spent my doctoral years at Boston University where I received a PhD in Physics (2011), advised by H. E. Stanley.

My research is primarily data-oriented, focusing on the evolution of large multiscale socio-economic systems by applying concepts and methods from complex systems, statistical physics, management and innovation science. Working with collaborators from a variety of disciplines, our research has been published in various multi-disciplinary journals such as Science, PNAS and Research Policy, and subsequently covered by the international media, such as the Boston Globe, Guardian, WSJ, Espectador, AAAS and Nature.

Research Interests
