My name is Sang Jung Kim (Sang). I am an assistant professor in the School of Journalism and Mass Communication at the University of Iowa. I study the interaction between technology, politics, and social identity, with particular attention to the mediating role of social media platforms and the spread of information to the public. I explore the identities of message creators and message receivers on social media platforms—including racial identity, gender identity, and political identity—and utilize both experimental methods and computational approaches to understand how consumers and creators of such content introduce and are impacted by biases.

My research has been recognized with top paper awards at major communication conferences, including the International Communication Association (ICA), the Association for Education in Journalism and Mass Communication (AEJMC), and the National Communication Association (NCA). I received an Excellence in Teaching Award in recognition of my teaching contributions at UW-Madison. 

My work has been published in flagship journals, including the New Media and Society, Journal of Communication, Communication Methods & Measures, Political Communication, International Journal of Press/Politics, Information, Communication, and Society, Journal of Computer-Mediated Communication, and Computational Communication Research, among other peer-reviewed journals.
