Blood Systems Research Institute (BSRI) is dedicated to advancing transfusion quality worldwide through scientific research, education and the promotion of evidence-based policies.

In the 50 years since our inception, BSRI has grown from a handful of researchers in the basement of Irwin Memorial Blood Bank to a distinguished institute engaged in research ranging from blood donor epidemiology to cellular therapy to virus discovery.

Following the tradition of our founder, Herbert Perkins, M.D., BSRI continues under the leadership of Director, Michael P. Busch, MD, PhD, to support the education and training of the next generation of researchers through fellowships, internships, mentoring and classes conducted in San Francisco and around the world.

Though the times have changed, our mission remains the same – an adequate and safe blood supply for all.
