Marcel Just is D. O. Hebb Professor of Psychology at Carnegie Mellon University. His research uses brain imaging (fMRI) in high-level cognitive tasks to study the neuroarchitecture of cognition. Just's areas of expertise include psycholinguistics, object recognition, and autism, with particular attention to cognitive and neural substrates. Just co-directs the Brain Imaging Research Center and is a member of the Center for the Neural Basis of Cognition at CMU.

Research

Mind reading

Marcel Just, Tom Mitchell, and colleagues at Carnegie Mellon University are conducting research on "thought identification" using fMRI. Using machine learning techniques, they have been able to identify patterns of brain activation that are reliably associated to the concept of different objects. These signature patterns could be generalized across different participants, so that the authors were able to correctly identify which object a participant was thinking of by analyzing the corresponding brain activation.
