About
I am a Postdoc at Northwestern University Institute on Complex Systems (NICO). I work with Brian Uzzi at the Kellogg School of Management. I am interested in computational social science, science of science, and social networks. I use data-driven and computational methods to examine the mechanisms involved in the production and dissemination of science and innovation. My research aims to generate insights that can help individuals and organizations lead and thrive in the knowledge economy. I earned my PhD from University of Michigan School of Information (UMSI), where I was advised by Daniel M. Romero.
