H. Richard Alexander, Jr., M.D.
Associate Chairman for Clinical Research, Surgery

H. Richard Alexander, Jr., M.D.

Dr. Alexander is an internationally recognized surgical oncologist and clinical researcher. He treats cancer patients at the University of Maryland Marlene and Stewart Greenebaum Cancer Center and is associate chairman for clinical research in the University of Maryland Department of Surgery.

Dr. Alexander came to the University of Maryland after spending 16 years at the National Institutes of Health, where he served as chief of the surgical metabolism section, chairman of the gastrointestinal malignancies section and deputy director of the NCI's Center for Cancer Research.

Dr. Alexander is recognized for developing innovative techniques to treat patients with advanced cancers of the gastrointestinal tract, especially the liver. One example is isolated hepatic perfusion, a way to circulate high doses of chemotherapy directly into the liver to treat patients with inoperable cancer. With this "closed loop" technique, only the liver is exposed to the chemotherapy, protecting other organs and minimizing the side effects of treatment.
