Hao Peng (彭浩)
Postdoctoral Fellow @ NICO
Kellogg School of Management
I am a Postdoctoral Fellow at Northwestern University Institute on Complex Systems (NICO) at Kellogg School of Management, working with Brian Uzzi.
I received my PhD from University of Michigan School of Information (UMSI), where I was advised by Daniel Romero.
I am interested in computational social science, science of science, social networks, and complex systems. My research studies the mechanisms involved in the production and dissemination of science and innovation. I obtained a master's degree in Data Science from Indiana University Bloomington, where I worked with Yong-Yeol Ahn and Filippo Menczer at CNetS. I received my bachelor's degree in Information Management from Sun Yat-sen University.
