Computational communication

What becomes
visible?

People. Platforms. Public information.

I study how search, social platforms, and generative AI shape the information people find and the claims they trust. At Missouri, I lead the Computational Communication Technology Lab, where we examine information access, credibility, and inequality in health and politics.

I am an assistant professor of Strategic Communication, jointly appointed in the Missouri School of Journalism and the Institute for Data Science & Informatics. Originally from Hanoi, I earned my M.A. at Ewha Womans University and my Ph.D. at the University of Wisconsin–Madison, advised by Dr. Hernando Rojas. At Cornell, my postdoctoral mentors were Drs. Jeff Niederdeppe and Drew Margolin.

Current work

AI and public information

My group is auditing Google AI Overviews across languages and over time. We examine how answers and sources change, how health guidance communicates uncertainty, and what these answers offer people seeking help.

Making information visible

My retrieval method recovered health videos that clinical search terms missed. Combining word embeddings, recommendation networks, and human review helps researchers examine the language people use online.

Algorithmic gatekeeping

The query matters.

Across three political topics, query wording was the primary source of differences in Google results. My audit separates query choices from variation associated with users’ political identities, changing how we interpret apparent search bias.

Credibility and public discourse

When “fake news” becomes an accusation

Accusations of “fake news” against political opponents were associated with affective polarization. I distinguish these uses from descriptions of false content, examining credibility labels as acts of political communication.
