The Blood Transfusion Service is a member of the NHLBI Clinical Trials Network in Transfusion Medicine and Hemostasis.

Dr. Dzik is a founding member of the Biomedical Excellence for Safer Transfusion (BEST) Collaborative. In 2002, Dr. Dzik led a large, international, multicenter BEST Study focused on blood grouping errors due to miscollected samples. A previous international study with this group focused on standardization of CD34+ cell counting during progenitor cell collections.   In 2008, he conducted a pivotal trial on universal leukoreduction. In 2016, he and his colleagues conducted a trial of oxygen delivery by stored blood.

In addition to these large clinical trials, Sunny Dzik's research interests include management of the coagulopathy of liver disease, clinical use of blood components, massive transfusion, biologic consequences of recipient exposure to allogeneic donor leukocytes, and patient safety in transfusion.
