Oct. 23, 2003 – Timothy J. Ley, MD, the Alan and Edith Wolff Professor of Medicine at Washington University School of Medicine in St. Louis, has been elected to the prestigious Institute of Medicine.

As a component of the National Academy of Sciences, the Institute of Medicine advances and disseminates scientific knowledge to improve human health. Election to the institute is considered one of the highest honors in the fields of medicine and health care. Members are chosen for their professional achievement and commitment to service. With election, members devote time on committees engaged in a broad range of studies on health policy issues.

Ley joined the School of Medicine faculty in 1986. He directs the Division of Oncology's stem cell biology section and serves as associate director of basic research for the Siteman Cancer Center at the School of Medicine and Barnes-Jewish Hospital.

Ley, who also is a professor of genetics, is renowned for advances in understanding the biology and genetics of acute myeloid leukemia. He has identified the mechanisms that cytotoxic lymphocytes use to kill tumor- and virus-infected cells and has shown that the same mechanisms cause severe tissue damage after allogeneic bone marrow transplantation. Additionally, he is known for his work to preserve the physician-scientist career track, encouraging physicians to pursue careers that involve both research and patient care.

Among his many honors, Ley was named Teacher of the Year in the Department of Medicine at Jewish Hospital in 1994 and received the Alumni/Faculty Award from the Washington University Medical Center Alumni Association in 1998. Ley is a past president of the prestigious American Society of Clinical Investigation.

Ley is among 65 new members announced earlier this week by the National Academy of Sciences.


The full-time and volunteer faculty of Washington University School of Medicine are the physicians and surgeons of Barnes-Jewish and St. Louis Children's hospitals. The School of Medicine is one of the leading medical research, teaching and patient-care institutions in the nation. Through its affiliations with Barnes-Jewish and St. Louis Children's hospitals, the School of Medicine is linked to BJC HealthCare.
