Gyo Hyun Koo, Ph.D.

Hello, and welcome to my website! 

I'm Gyo "Hyun" Koo, an Assistant Professor of Communication, Culture, and Media Studies at Howard University. My research focuses on how communication technologies shape people's knowledge, perceptions, and behaviors, with particular attention to their implications for democracy and public health. 

I hold a Ph.D. in Journalism and Media from The University of Texas at Austin, where my dissertation examined how news exemplifications influence perceptions of political polarization. At Howard, I teach courses in Communication Theory, Political Communication and Public Opinion, Media Ethics, Data Science, and Health Communication and Technology.
