Hannah Metzler is a psychologist and cognitive scientist at the Complexity Science Hub, where she has been a postdoctoral researcher since March 2020. She leads the project “Emotional Misinformation Spreading” since 2021.

Her current research focuses on social media and misinformation, especially the role of emotions and social identity in shaping beliefs and the sharing of misinformation. At the CSH, she has further investigated collective emotions and mental health during the COVID-19 pandemic, and contributions of traditional and social media content to suicide prevention. For her research, she has used methods from computational social science and psychology, such as large-scale text analysis, machine learning, and online experiments.

Hannah holds a master’s degree in psychology from the University of Vienna, where she studied stress, hormones, and gender from a cognitive neuroscience perspective. She completed her PhD in social and affective neuroscience at Sorbonne University and the École Normale Supérieure in Paris, focusing on how social power influences the perception of faces and emotions, using behavioral, hormonal, and physiological methods.
