Machine Learning Team
Functional Magnetic Resonance Imaging Core Facility
Francisco Pereira leads the Machine Learning Team within the Section on Functional Imaging Methods at the National Institute of Mental Health, in Bethesda, Maryland. Prior to that, he was a staff scientist at Siemens Healthcare, where he managed the Computational Neuroscience program. He did his postdoc at the Princeton Neuroscience Institute, working with Matt Botvinick and Ken Norman, as well as anyone stopping by his office with an interesting question and chocolate. He received a Ph.D. in Computer Science and Neural Basis of Cognition from Carnegie Mellon University, where he worked with Tom Mitchell and Marcel Just, and an undergraduate degree in Computer Science from Universidade do Porto. He promises not to talk about himself in the third person if you come to his office.
The mission of the Machine Learning Team (MLT) is to support researchers in the NIMH intramural research program (IRP) who want to address research problems in clinical and cognitive neuroscience using machine learning approaches.
We do this by consulting with individual researchers and guiding them in the use of the appropriate tools and methods, or by taking on the analysis process ourselves, if this is more expedient. In parallel, we develop new methods and analysis approaches, motivated by the needs of researchers or by the practical possibilities arising from advances in the field.
