Dr. Junqian (Gordon) Xu received his PhD degree from the Biomedical Magnetic Resonance Lab (BMRL) at Washington University in St. Louis in 2007. He completed his postdoctoral training in the Multiple Sclerosis Center at Washington University School of Medicine. In 2010, Dr. Xu joined the WU-Minn consortium of the Human Connectome Project (HCP) and had worked on multiband EPI sequence development at the Center for Magnetic Resonance Research (CMRR), University of Minnesota for two years before joining Mount Sinai in 2012 to establish a neuroimaging laboratory using advanced in vivo magnetic resonance imaging (MRI) techniques.

Advanced magnetic resonance (MR) techniques in neuroimaging
- brainstem and cervical spinal cord MRI at ultra-high field.
- functional and structural assessment of the spinal cord and optic nerve.
- functional MRI of small nuclei in the brain, such as the habenula.
- Neuroimmunology of Anhedonia in Adult Major Depressive Disorder
The purpose of this study is to find out if inflammation in the body and brain are related to feelings of loss of pleasure. Loss of pleasure can be easily measured and is related to specific linked brain regions. Our laboratory and others have shown that inflammation measured ...
- Neurophysiological biomarkers for personalized spinal cord injury rehabilitation
The purpose of this study is to better understand how patients' ability to move and feel after spinal cord injury (SCI) relates to the results of their brain and spinal cord magnetic resonance imaging (MRI) after spinal cord injury. The research MRI examination in this study t...
- Imaging optic nerve function and pathology
The purpose of this magnetic resonance imaging (MRI) study is to take clear pictures of a patient's optic nerve to see how they are affected by glaucoma. We will take high-resolution pictures of the optic nerve using MRI to evaluate how patients see through their eyes. We will...
