1998-present: Founder and Director of the noontime Chancellor's Concert Series that brings free, live classical music to the all-science UCSF campus 15 times a year
1980-present: Work in the prevention of several diseases transmitted by blood and blood transfusion:
1. Prevention of hepatitis B transmission from mother-to-infant, by perinatal administration of hepatitis B immunoglobulin and hepatitis B vaccine to infants of carrier mothers. After this work was published and provided evidence that vaccination of infants was safe and effective, the US Advisory Committee on Immunization Practices recommended routine hepatitis B vaccination for infants in 1991.

2. Prevention of transfusion-associated diseases associated with transfusion by the use of autologous blood.

3. Prevention of unnecessary plasma transfusion, by determining that there is no increased risk of bleeding in patients with mild coagulopathy who underwent percutaneous needle procedures.

REF: McVay PA, Toy PT. Lack of increased bleeding after paracentesis and thoracentesis in patients with mild coagulation abnormalities. Transfusion. 1991 Feb; 31(2):164-71.
4. Prevention of bleeding from dilutional coagulopathy in trauma patients massively transfused with packed red blood cells, by earlier transfusion of plasma and/or whole blood.

5. Prevention of unnecessary transfusions by physician education and prospective review of blood orders.

6. Prevention of unnecessary red blood cell transfusion, by examining the red blood cell transfusion trigger level. We determined that only hemoglobin levels below 7 g/dL are associated with organ impairment (cognitive dysfunction) during acute normovolemic anemia in normal humans.

7. Prevention of hyperkalemia (high potassium levels) and associated cardiac abnormalities in pediatric cardiac surgery patients, by washing stored red blood cells prior to transfusion on the morning of surgery.

8. Prevention of exsanguination in acutely bleeding hospitalized patients, by establishing an Emergency Release procedure so that blood and blood components are rapidly available.
REF: Weiskopf RB, Webb M, Stangle D, Klinbergs G, Toy P. A procedure for rapid issue of red cells for emergency use. Arch Pathol Lab Med. 2005 Apr; 129(4):492-6.
REF: UCSF Blood Bank procedures
9. Prevention of most hemolytic transfusion reactions associated with transfusion of Group O plasma, by not transfusing group O plasma to group A and AB patients (most ABO hemolytic reactions associated with transfusion of group O plasma are in group A patients, and rarely in group B patients).
REF: UCSF Blood Bank Procedures
10. Prevention of transfusion-related acute lung injury (TRALI) by establishing a clinical definition, determining the transfusion and patient risk factors, and observing the efficacy of transfusing plasma from predominantly male donors in reducing TRALI incidence.

11. Prevention of TRALI in pediatric patients undergoing spine surgery, by identifying transfusion of maternal blood as an important risk factor.
