About the Wallis Lab

We are part of the Department of Psychology and Helen Wills Neuroscience Institute at the University of California at Berkeley. Our research focuses on understanding the functional organization of the frontal cortex at the single neuron level. Our methods use sophisticated behavioral paradigms, multichannel recording and computational analysis of neuronal data. We aim to understand the neuronal mechanisms underlying a number of high-level cognitive and behavioral processes, including decision-making, learning and working memory. The goal of our research is to guide the development of the next generation of treatments for mental illness.

We're hiring!

A postdoctoral position is available to study neural mechanisms underpinning decision-making, reward processing and executive control. For information about applying please click here.
