Administrative Leadership

  • Rui M. Costa, DVM, PhD

    Director and Chief Executive Officer

    Rui Costa is director and chief executive officer of Columbia’s Mortimer B. Zuckerman Mind Brain Behavior Institute and a professor of neuroscience and neurology at Columbia's Vagelos College of Physicians and Surgeons. In his role Dr. Costa is responsible for the administrative, financial and scientific management of the Institute. Prior to being named director, he served as associate director and CEO of the Zuckerman Institute from 2017-2019. Dr. Costa has substantial experience in institutional leadership for neuroscience research. Prior to joining Columbia in 2016, he was Director of Research at the Champalimaud Centre for the Unknown in Lisbon, Portugal.

    Dr. Costa is an expert in movement and behavior in health and in disease. To gain insight into these brain processes, he has developed powerful new approaches and methodologies that harness genetics, cutting-edge imaging technology and brain-machine interfaces. Using these tools, his laboratory recently identified the mechanism by which the brain initiates a movement, such as taking a first step. Because problems with movement initiation are a hallmark sign of Parkinson’s disease, deciphering how this process goes awry in Parkinson’s is critical for developing more effective treatments. Dr. Costa’s research has also shed light on how the brain combines distinct movements into a seamless sequence, called ‘action chunking.’ These investigations have led to a deeper understanding of how the brain learns to repeat movements that elicit a feeling of pleasure, while also providing insight into psychiatric disorders characterized by compulsive or repetitive movements and actions, such as autism and obsessive-compulsive disorder.

    Dr. Costa was an International Early Career Scientist at the Howard Hughes Medical Institute from 2012-2017. In 2017, he was awarded the Ariëns Kappers Award from the Royal Netherlands Academy of Arts and Sciences for his contributions to the field of neuroscience. In 2014, Dr. Costa was knighted Commander of the Order of Sant'Iago da Espada by the President of Portugal. In 2014, he also received the Young Investigator Award from the Fondation Louis-Jeantet and in 2012 from the Society for Neuroscience.
