	Counter to the narrative of the ~~current~~ AI industry, the most impressive capabilities of the brain are not yet understood. Unlike current AI systems, brains are always involved in controlling closed action-perception loops with the environment, and learning data has to be actively gathered. In this particular setting, what is natural intelligence? ~~How does such a setting shape the~~ objectives and strategies ~~of learning~~ in ~~brains~~? How do brains achieve energy and data efficiency which supersedes current AI by many orders of magnitudes?		Counter to the narrative of the AI industry, the most impressive capabilities of the brain are not yet understood. Unlike current AI systems, brains are always involved in controlling closed action-perception loops with the environment, and learning data has to be actively gathered. In this particular setting, what is natural intelligence? What objectives and strategies enable brains to learn in such a setting? How do brains achieve energy and data efficiency which supersedes current AI by many orders of magnitudes?
	In collaboration with experimental neuroscience labs, my lab investigates the theoretical principles of computing and learning in areas of perception, navigation and memory. At the same time, I am interested in dynamical systems and neurobiological design principles for building next generation artificial intelligence systems.
