Diamantis Petropoulos Petalas

I am an Assistant Professor of Psychology at the American College of Greece (Deree), with a background in cognitive psychology, political neuroscience, and media psychology. My academic journey spans sociology, neuroscience, and psychology, earning degrees from Panteion University, the University of Athens, and the University of Amsterdam, before completing my PhD in Communication Science at Radboud University Nijmegen.

My research focuses on understanding human cognition and behavior in political, economic, and media contexts, using experimental, behavioral, and neurophysiological methods such as EEG and psychometric assessments. I have held postdoctoral positions at Vrije Universiteit Amsterdam and the University of Amsterdam, investigating social media effects and the neuropsychological correlates of political ideology.

As an educator, I teach undergraduate and honors courses in cognitive and political psychology, research methods, and media psychology. My teaching philosophy is centered on fostering critical thinking and real-world application of psychological concepts. I also provide consultancy on research design, team dynamics, and psychological assessment for individuals, professionals, and organizations.
