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.
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. Bertrand’s main focus are collective intelligence, social influence and cognitive biases in human groups.
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 human groups to uncover the dynamics of collectives.
Marta just started her 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 expert, providing key support for conducting online studies.
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 programmer, 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.
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 works in our group as a research assistant helping out with various tasks including database management, organizing lab participants and running experiments.
