The author of more than 300 scientific publications, Rosand, with his program in cerebrovascular health, conducts research in partnership with thousands of volunteer patients and families to prevent strokes and improve recovery from stroke and other brain injuries. Their focus is discovering the role of genetics and using those discoveries to speed the development of new treatments. The lab is a leading contributor to the performance and analysis of high-throughput genome-wide association and sequencing studies in stroke and related traits. In order to accelerate these discoveries, Jonathan founded the International Stroke Genetics Consortium to bring together the world’s pre-eminent stroke investigators, and launched the NIH-funded Platform for Accelerating Genetic Discovery for Cerebrovascular Disease to share data widely. The Consortium is now composed of more than 100 investigators from six continents who work collaboratively on an unprecedented scale and publish their work in the world’s leading journals.
