David B. Sacks, MB ChB

Biosketch

David B. Sacks received his medical training at the University of Cape Town, South Africa. He completed residencies in Internal Medicine at Georgetown University affiliated hospitals in Washington, D.C. and in Clinical Pathology at Washington University School of Medicine in St. Louis and is board certified in both disciplines. After completing fellowship training in Clinical Chemistry at Washington University School of Medicine, he joined the Department of Pathology at Harvard Medical School and Brigham and Women's Hospital, where he was both Medical Director of Clinical Chemistry and Director of the Clinical Pathology Training Program. He joined the NIH as Chief of Clinical Chemistry in 2011.

The scientific work in his research laboratory is in the general area of intracellular signal transduction, with a focus on calcium and calmodulin signaling. His research has been funded for over 20 years by grants from the National Institutes of Health, the American Diabetes Association, the Diabetes Action Research and Education Foundation, the Susan G. Komen Breast Cancer Foundation, the U.S. Army and the Burroughs Wellcome Fund.

Dr. Sacks's primary clinical focus is in diabetes mellitus, with an emphasis on the interface between the clinical laboratory and patient care. In this endeavor, he has worked closely with the American Diabetes Association. He is Chair of the National Glycohemoglobin Standardization Program (NGSP) steering committee. He was Director of the Young Investigator Program of the Academy of Clinical Laboratory Physicians and Scientists (ACLPS) from 1995-2001 and later served as President of ACLPS. In addition, he serves on or chairs several other national and international committees. He was elected a Fellow of the Royal College of Pathologists in 1998.

Dr. Sacks has published more than 150 articles in scientific journals. He has served on the editorial board of Clinical Chemistry since 1995 and is currently an Associate Editor of the journal. In addition, he has served on several other editorial boards, including The Journal of Biological Chemistry, The American Journal of Pathology and The American Journal of Clinical Pathology and is a member of the editorial advisory panel of The Biochemical Journal.
