Director, Neuropathology Services at UMMC Fairview

In addition to a full-time practice at University of Minnesota Medical Center, Fairview, Dr. Clark is a consultant at Hennepin County Medical Center and the Minneapolis Veterans Affairs Medical Center. He is active in the teaching of pathology residents on both the anatomic pathology and neuropathology specialty rotations. Residents from the Departments of Neurology and Neurosurgery rotate on his service and he teaches a lecture series for both programs. He also directs the neuropathology section of the second year medical student pathology course.

Research Interests

Dr. Clark’s research activities involve pathological studies of cerebellar ataxia both in human disease and experimental animal models. He is involved as co-investigator on two NIH grants related to investigation of animal models of spino-cerebellar ataxia type 1 and co-investigator on an NIH program project grant studying the CNS aspects of myotonic dystrophy.

Educational Background

  • Washington University School of Medicine, St. Louis, MO (1978), M.D./Ph.D.
  • Barnes Hospital / Washington University, St. Louis, MO (1982), Residency (Anatomic Pathology and Neuropathology)

Board Certification

Anatomic Pathology, Neuropathology


Dr. Clark has written on a number of subjects, including ataxia, middle cerebral artery dissection, tauopathies, treatment of brain tumors with stereotactic radiosurgery, and increased expression of nitric oxide synthase and cyclo-oxygenase-2 related to cerebral ischemic injury. He is a member of the Editorial Board of Brain Pathology, Journal of Neuropathology and Experimental Neurology, Acta Neuropathologica and Neurobiology of Disease.
