Charlie grew up in New York, went to Harvard College and came to the Bay Area in 1970 with his wife Lanie. He went to Stanford Medical School and received his internal medicine training at Stanford. He then went to UCSF where he was a fellow in Hematology/Oncology. The next 30 years he was a member of the faculty of UCSF, the Director of the Bone Marrow Transplant and Leukemia/Hematologic Malignancies Program, and co-leader of the Hematologic Malignancies Program at the UCSF Comprehensive Cancer Center. He was the holder of the Krishnamurthi Endowed Chair until his retirement in 2010. His research focused on the development of improved treatments for patients with leukemia and related diseases.
In 2008, Charlie started fly fishing and quickly came to love steelhead fishing. He participated in the first annual Cal Trout Trinity steelhead trip, and has made this an annual event. He is also interested in backpacking, hiking, alpine skiing, and scuba diving.
He has also deepened his interest in classical music, is active on the Board of Cal Performances at UC Berkeley, and with retirement has started playing the piano. He is fortunate to have both his children living in the Bay Area, and is very involved with his grandchildren.
