Loewenstein's lab

We are an interdisciplinary laboratory, interested in computational neuroscience and computational cognition. Research in the lab in recent years has primarily revolved around the neural mechanisms and computational principles underlying different types of learning. However, we are easily distracted and study whatever question we find interesting.
