Raymundo Báez-Mendoza, PhD

The ultimate goal of my research is to understand the behavioral and neuronal mechanisms governing cognition, particularly our ability to navigate social interactions.

I was born and raised in Mexico City where I studied Psychology at UNAM -the largest public university in Latin America. I then studied my masters with Nikos Logothetis and Kari Hoffman at the Max Planck Institute for Biological Cybernetics in Tübingen, Germany, followed by PhD Studies at Cambridge University working under the supervision of Wolfram Schultz. Where I studied how the basal ganglia responds to rewards in social contexts.

I did my Postdoc with Ziv Williams at the Department of Neurosurgery of Massachusetts General Hospital to uncover the neuronal basis of social interactions. I became an instructor in research in 2018.

I began my current position as Junior Group Research Leader in 2022.
