Zachary Mainen, Ph.D.

Fundação ChampalimaudZachary Mainen’s website

Zachary Mainen is a neuroscientist whose research focuses on the brain mechanisms of decision making. He studied psychology and philosophy at Yale University, received his doctorate in neuroscience from the University of California, San Diego, and held a faculty position at Cold Spring Harbor Laboratory, before moving to Lisbon in 2007 to found the Champalimaud Neuroscience Programme, where he is now the director. His work has been recognized by the Advanced Grant of the European Research Council and by election to the European Molecular Biology Organization. Mainen’s research explores brain function, especially decision making, using theory-driven experimental approaches. His laboratory helped to pioneer the use of quantitative behavioral paradigms in rodents and combines those approaches with electrophysiological, optical and genetic techniques to study neural representation and computation. He has a long-standing interest in the issue of how noise and uncertainty impact neural systems and behavior, and our understanding of these processes. His lab is currently exploring these questions in the context of odor-guided perceptual decisions and learning, the timing and selection of simple actions, and the role of the neuromodulator serotonin in behavior and cortical function. This work touches on philosophical issues surrounding causality, free will, knowledge and belief.
