Yotam Ophir (PhD, University of Pennsylvania, 2018) studies political and science communication (media effects, persuasion, misinformation, conspiracy theories and extremism), using mixed-method approaches, including computational text mining, network analysis, experiments, and surveys. Dr. Ophir’s work was published in journals such as the Proceedings of the National Academy of Sciences (PNAS), American Journal of Public Health (AJPH), Journal of Communication (JOC), and Communication Methods and Measures (CMM). His coauthored book, “Democracy amid Crises: Polarization, Pandemic, Protests, & Persuasion” was published in 2022 by Oxford University Press.
