Dr. Paz Soldán is assistant professor in the Neuroimmunology Division of Neurology at the University of Utah. His clinical interests focus on multiple sclerosis (MS), neuromyelitis optica (NMO), and other inflammatory or demyelinating diseases of the central nervous system. His interests extend to autoimmune neurologic diseases—those primarily affecting the nervous system, those occurring with rheumatologic disease, and those occurring in the setting of cancer (paraneoplastic). He also has interest in general clinical neurology.
