Senior Research Scientist
Ralf is the PI of the research group. Ralf did his PhD in behavioral ecology at the Wageningen University, studying the role of individual differences in social information use and collective movement in bird flocks. After his PhD, Ralf joined the lab of Jens Krause as a postdoc working on collective decision making in fish and human groups. In 2016 Ralf established his own research group at the MPIB where he works at the interface of behavioral ecology, social psychology and collective behavior. Ralf is also an external PI in the Science of Intelligence Excellence Cluster, and a guest researcher at the Leibniz Institute of Freshwater Ecology and Inland Fisheries.
Alan recently finished his PhD in our research group in which he investigated the cognitive mechanisms underlying decision making in human collectives. Alan is continuing his research with us as a Postdoc further expanding his exciting work on applying social drift diffusion models to social systems to uncover the temporal dynamics of collectives.
Susanne finished her Master program Mind and Brain and is currently in her first year of the Max Planck School of Cognition. As part of that year, Susanne is conducting a 3 month lab rotation with us in which she is investigating what underlies decisions of group members to share social information, and how this, in turn, shapes collective performance.
Master Student – soon PhD Student
Mubashir (Mubs) is pursuing his Master in Brain and Cognitive Sciences at the University of Amsterdam. Mubs research interest are social decision making with a focus on experimental methods and computational modeling. Mubs is currently conducting his Master thesis in our group studying how time pressure affects the cognitive processes underlying the identification of online misinformation. Per September Mubs will join the lab as a PhD student.
Alexander is currently conducting a Master in Psychology at the Heidelberg University. Alexander has a broad interest in social behavior and social cognition, and is especially interested in how techniques from cognitive psychology can be applied to study social decision making. Alexander is doing his Master thesis with us, investigating how integrating decision maker’s metacognition can improve wisdom of the crowd estimates.
Research Assistant / Master Student
Marta is conducting a Master in Neural Systems and Computation at the ETH in Zurich. Marta is interested in computational neuroscience and the application of machine learning techniques to solve complex societal problems. Marta works in our group as a programming RA, providing vital support for conducting online interactive group studies. The to-go person for any debugging.
Research Assistant / Master student
Deyan is pursuing his Master in Informatics at the Free University of Berlin. Deyan has a keen interest in programming and neuroscience. Deyan works in our lab as a programming RA, bringing his skills in C++, Java and Python to live in projects ranging from real-time communication between tablets for collective decision making studies, to online studies, to programming apps for museum expositions.
Cheyenne is in her second year of her study Psychology at the Jacobs University in Bremen. She has a fascination for social learning strategies, collective intelligence, and social-cognitive disorders. Cheyenne is conducting an internship with us building a large-scale database on studies on misinformation brushing up her skills on data tidying in R and version control in GitHub.
If you are interested in the work we do and joining the group or collaborating, please get in touch.
After completing his PhD in social physics at Toulouse university, studying collective human behavior using techniques from statistical physics, Bertrand joined our group as a postdoc. During his stay with us Bertrand focused on collective intelligence, social influence and cognitive biases in human groups. After spending three years with us Bertrand moved to the Singapore University for his next postdoc in cooperation with the ETH in Zurich. Website
Ruth is finishing her Masters in Psychology at the Friedrich-Schiller University in Jena. Ruth has a keen interest in how identities shape group processes. Ruth has conducted a 3 month internship with us in which she started to build a large-scale database on studies on misinformation brushing up her skills on data tidying in R, archiving metadata (rjson) and version control in GitHub.
Aaron finished his bachelor in Psychology at the Heidelberg Unversity, and is about to start a Master in Psychology at the University of Amsterdam. Aaron’s main research interest lies in the field of cognitive social psychology. In his 3-month internship with us Aaron used machine learning techniques for optimizing wisdom of crowd accuracy in large datasets. website
Ethan is pursuing his Master in Cognitive Linguistics at the University of Potsdam. For his Master project, Ethan is studying lexical development in infants using eye tracking at the BabyLab at the University of Potsdam. Ethan worked in our group as a Research Assistant helping out with various tasks including database management, organizing lab participants and running experiments. Website
