Dr. Peter Calabresi serves as the Director of the Multiple Sclerosis Center, focusing on the diagnosis and management of MS. He is the principal investigator on several clinical trials and oversees research projects seeking to create new anti-inflammatory and neuroprotective therapies for MS.

Dr. Peter Calabresi received his undergraduate degree from Yale University and his medical degree from Brown University. He then completed an internship and residency training in internal medicine at Strong Memorial Hospital. He went on to complete a fellowship in neuroimmunology at the National Institutes of Health.

Dr. Calabresi is also directing a longitudinal magnetic resonance imaging (MRI) study using new ways of assessing nerve fiber and myelin integrity in the brain and spinal cord. These approaches may provide more information than conventional MRI, which is heavily weighted towards measuring inflammation.

In April 2017 Dr. Calabresi was elected to the Association of American Physicians. He currently sees patients at the Johns Hopkins Outpatient Center in Baltimore on Wednesdays. more
