Anita Eerland is an Associate Professor at the Behavioral Science Institute and Department of Communication Science at Radboud University. A champion of open science in the Netherlands, she founded the first Dutch Open Science Community in 2018 and now serves on the board of the International Network of Open Science and Scholarship Communities. Her research examines vaccination communication and behavioral decision-making. She brings extensive experience in multilab research designs and is the Principal Investigator of the NWO-funded EPPM replication project.
Founding Members
Five communication scientists leading the Global Initiative for Replication in Communication Science.
Lisa Vandeberg is an Associate Professor of Communication Science at the Behavioral Science Institute, Radboud University. Her research focuses on health communication, particularly vaccination communication and prosocial persuasion. She examines how communication influences health decision-making across diverse populations, with expertise in narrative persuasion, cultural adaptation of health campaigns, and cognitive biases in health information processing. Her work bridges communication science and public health practice.
Marieke Fransen is a Full Professor at the Behavioral Science Institute, Radboud University, specializing in persuasion and resistance to persuasion. She directs the Resistance Lab and investigates how people can protect themselves against manipulative messages while also examining how persuasive communication can be ethically enhanced. Her research on inoculation theory and psychological resistance has applications to misinformation prevention and vaccine communication. She brings expertise in both the sender and receiver perspectives of persuasive processes.
Philipp K. Masur is Associate Professor at the Department of Communication Science at Vrije Universiteit Amsterdam, Managing Director of the Digital Media and Behavior Lab, and Chair of the Research Ethics Review Committee of the Faculty of Social Sciences. His research investigates privacy behavior, social media, and digital well-being. He has conducted more than 11 direct replication studies, co-authored the replication taxonomy for experimental communication science (Vermeulen, Masur, Beukeboom & Johnson, 2024, Media and Communication) and the open science agenda for the field (Dienlin, Johannes, Bowman, Masur et al., 2021, Journal of Communication).

Ivar Vermeulen is Associate Professor at the Department of Communication Science at Vrije Universiteit Amsterdam. A pioneer of open science in communication research, he initiated the Open Science Network for communication science in 2013, which grew into national and international events. In 2018, he organised the first large-scale community vote — 267 communication scientists — to identify the studies most in need of replication, with Witte (1994) emerging as a top priority. He co-authored the replication taxonomy for experimental communication science (Vermeulen, Masur, Beukeboom & Johnson, 2024, Media and Communication).
