I am a fourth-year PhD student in Psychology at the Center for Adaptive Rationality (ARC) at the Max Planck Institute for Human Development in Berlin. As part of the Reclaiming Individual Autonomy and Democratic Discourse Online (RAO) project (funded by a Volkswagen Foundation grant), my research seeks to make the Internet a better place. During my doctoral studies, I also spent some time as a visiting PhD student at the Network Science Institute at Northeastern University.

Prior to joining ARC, I earned a Master of Behavioral and Decision Sciences from the University of Pennsylvania. I also completed an MSc in Marketing with distinction (Trinity College Dublin) and a BA in Business Administration (Provadis School of International Management and Technology).
