Marcelo Mattar is an Assistant Professor of Psychology and Neural Science at New York University. He holds a PhD in Psychology and a Master’s in Statistics from the University of Pennsylvania, and a Bachelor’s in Electronics Engineering from the Aeronautics Institute of Technology in Brazil. Prior to his current role, Dr. Mattar was a postdoctoral researcher at Princeton University under the mentorship of Nathaniel Daw and at the University of Cambridge’s Department of Engineering, working with Máté Lengyel. Dr. Mattar's research integrates neuroscience, psychology, and computational modeling to explore how the brain supports flexible decision-making. Focusing on the interplay of learning, memory, and planning, his lab uses computational modeling, behavioral experiments, and neural recordings to understand how the brain builds internal models from experience to simulate the future and guide choices.
