Dr. Tabak was appointed as the principal deputy director of the NIH on August 23, 2010. Previously he served as acting principal deputy director of the NIH from November 13, 2008 through August 14, 2009. Named as the director of the National Institute of Dental and Craniofacial Research (NIDCR) in September 2000, he held that post through August 2010. Prior to joining NIH, Dr. Tabak served as the senior associate dean for research and professor of dentistry and biochemistry & biophysics in the School of Medicine and Dentistry at the University of Rochester in New York. A former NIH MERIT recipient, Dr. Tabak has received several honors and awards for his work including being elected as a member of the Institute of Medicine of the National Academies. He has also received teaching awards for his work with both graduate and medical students.
