Dr. Violet Cheung (ORCiD 0000-0003-2706-025X) is a co-chair and a professor in the department of psychology at the University of San Francisco. Her research on mass emotions started after 9/11 while she was completing her doctorate degree at UC Berkeley. She examined angry responses to the terrorist attack and how the public sentiment precipitated the U.S. to go to war. She now focuses on anxious and fearful responses in the new contexts of cyber insecurity, the migrant crisis, and the COVID pandemic. She also uses big data analytic tools to examine public sentiments on social media. Her research was funded by the American Psychological Association and her first-author publications appeared in journals such as Political Psychology, Emotion, and Current Opinion in Psychology.
