Hi! I'm Marcelo Mattar, a neuroscientist working with Nathaniel Daw at Princeton and Máté Lengyel at Cambridge.
I use theoretical and experimental approaches to understand how we simulate the future to guide our decisions.

Starting in July 2020, I will be an Assistant Professor at the Department of Cognitive Science at UC San Diego. Please contact me if you would like to join my lab as a research assistant, PhD student, or postdoc.
