About

I am a PhD candidate in School of Information at University of Michigan. I am advised by Daniel Romero. My research is in computational social science and science of science. I am interested in studying how social factors influence the process of scientific publishing and the dissemination of knowledge, with a goal to improve the equity and quality of science, and amplify its societal impact.
