We are interested in finding rules of group behavior. We focus on decision-making and learning in groups, how information is aggregated, how consensus is reached and how individuality impacts group behavior. 

Our approach includes building new theories and testing them experimentally in zebrafish, mice and humans using a variety of techniques from Neurobiology, Behavioral Ecology, Molecular Biology, Psychology and Sociology. 

We are also developing new tools to improve the quality of behavioral data and its analysis and adapting new technologies to study group behavior.

We have doctoral and postdoctoral positions available.
