Research Interests

The investigation of alterations in the functional and structural neurobiology of adolescent offspring of schizophrenia patients using functional and structural MRI. (Supported by NIMH and Children’s Research Center of Michigan; Key research personnel: E. Murphy, D. Goradia. Key Collaborators: M. S. Keshavan).

The investigation of alterations in fronto-hippocampal functional pathways in schizophrenia during learning and memory dynamics.

Murphy. Key Collaborators: P. Erdi, M.S. Keshavan, J. Stanley, S. Eickhoff, P. Brambilla)

The investigation of common and unique cortical and sub-cortical pathways of vulnerability to schizophrenia or bipolar disorder using fMRI and magnetic resonance spectroscopy (MRS). (Supported by NARSAD and CRCM; Key research personnel: E. Murphy, R. Condon, D. Goradia. Key Collaborators: J. A. Stanley, M. Phillips, B. Birmaher, M. Tancer, M. S. Keshavan).
