Our decisions, learning experiences and emotions depend on other people, and conversely the patterns in collectives result from interacting individuals. What are the rules of interaction? Which patterns can emerge?
Our aim is to reach a quantitative understanding of individual and collective behavior, including collective coordination, collective decisions and collective intelligence. We approach this problem using a variety of techniques, including behavior, mathematical modelling, machine learning and artificial intelligence, virtual reality, neurobiology, and molecular biology. We chose to implement this approach in zebrafish and humans.

Collective Behavior de Polavieja Lab gonzalo.polavieja@neuro.fchampalimaud.org
Theory
We are developing new theoretical frameworks to understand collective behavior, including approaches adapting Bayesian Theory, Control Theory or Reinforcement Learning. We apply these approaches to better explain how decision-making, learning or group coordination takes place in groups.
Experiments in Zebrafish and Humans
Our setups include custom-made behavioral arenas for zebrafish, brain imaging in zebrafish, psychophysics and virtual reality for humans and molecular biology.
Machine Learning and Artificial Intelligence
We are developing and adapting supervised and unsupervised techniques from machine learning and artificial intelligence for extraction of relevant data in experiments and to quantify individual and collective behavior.
