Hey, welcome to my homepage! 

I'm Mingxuan (Elaine) Liu. I'm an Assistant Professor in the Department of Communication at University of Macau, my alma mater. I received my Ph.D. in the Annenberg School for Communication and Journalism with a cognate area in Psychology at University of Southern California in 2023, advised by Professor Lynn Miller. After that, I worked as a postdoctoral fellow at the Spiegel Research Center in Medill School of Journalism, Media, Integrated Marketing Communications at Northwestern University from 2023 to 2024. 

I hold an M.A. degree from the Department of Communication at UC Davis and a B.S.S. degree from the University of Macau, where I majored in Communication and minored in Psychology. Additionally, I was a member of the Honours College at the University of Macau, class of 2016. 

Outside academia, I have worked as a public relations intern at the Venetian, Sands China, and as a Global Food Initiative intern at the strategic communications unit for the University of California Agriculture and Natural Resources.

My areas of specialization include:

My work has been published in flagship peer-reviewed journals in Communication, including New Media & Society, Media Psychology, Health Communication, Computers in Human Behavior, Mobile Media & Communication, Media and Communication, among others. 

I am currently recruiting PhD students to join my research team at UM (Master's and undergraduate students are also welcome). If you have an interest in digital media, user psychology, and behavior, with a focus on quantitative methods, I encourage you to apply. No prior publications are required, but academic integrity and commitment are essential. For questions, please reach out to mxliu@um.edu.mo.
