Siyuan Liu s a neuroimaging scientist who works at the National Institute of Mental Health. Until recently, he worked as a research fellow with Dr. Allen Braun in the Language Section, National Institute on Deafness and Other Communication Disorders (NIDCD). His work at the NIDCD focused on understanding how language is initiated in the brain and how this process is disrupted by communication disorders, through the use of functional and anatomical imaging techniques. In this context he has conducted studies of literary creativity that seek to link the creative process, the quality of the creative product and the impact of expertise to functional interactions between prefrontal and parietal systems. This model has recently been extended to include dynamic measures of entropy that appear to play a central role in these processes. Dr. Liu holds a Ph.D. in bioengineering from the University of Illinois at Chicago.
