The current ACGME-approved Vascular Neurology Fellowship Program builds on the rich tradition of training stroke fellows at the University of Iowa and capitalize the institutional excellent clinical, training and research resources. We are committed to training outstanding physicians in vascular Neurology.

University of Iowa is one of the 25 RCCs nationally part of the NIH-StrokeNet network.

The Group at the University of Iowa is involved in many intra and extramural research projects. Research and scholar activities are highly encouraged. Fellows will have the opportunity to be mentored in their research enterprises.
These are some of the latest publications:
