I'm Mingxuan (Elaine) Liu, an Assistant Professor in the Department of Communication at the University of Macau. My research focuses on:
Emerging Information and Communication Technology (ICT): Investigating how emerging technologies shape user engagement, behavior, health, and well-being, with a focus on the video game, streaming, and journalism industry;
Causal Inference: Leveraging observational data, natural experiments, randomized experiments, psychophysiology experiments, and panel self-reports to understand the causal mechanisms underlying user behavior change.
My work has been published in flagship peer-reviewed journals in Communication, including Journal of Computer-Mediated Communication, New Media & Society, Media Psychology, Health Communication, Computers in Human Behavior, Mobile Media & Communication, Media and Communication, among others.
I earned my Ph.D. at the Annenberg School for Communication and Journalism with a cognate area in Psychology at the University of Southern California. 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. I hold an M.A. degree from the Department of Communication at UC Davis and USC, and obtained a B.S.S. degree from the University of Macau, where I majored in Communication and minored in Psychology.
I am currently recruiting PhD students to join my research team at UM. 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. Master's and undergraduate students are also welcome to email me to inquire about research opportunities.
Disclaimer: I do not authorize any grad school application agencies to use my information or recruit graduate students for me, and I strongly discourage students from using these services for their applications. Originality and innovation are fundamental in research. If you can't write your own application materials, you may not be ready for academia.
