Curt W. ReimannCurt W. Reimann, Ph.D.

Chair: SC3: Subcommittee on Quality Management and VA Process Integration with DTRA Nuclear Test Personnel Review Program
Dr. Reimann is an expert in quality management. He earned a Ph.D. in chemistry from the University of Michigan and served in a variety of research and management positions at the National Institute of Standards and Technology (NIST). He served as first Director (1987—1995) of the Malcolm Baldrige National Quality Award, led by NIST. The award, created by Public Law 100-107, promotes quality awareness, recognizes excellent U.S. organizations, and publicizes successful quality strategies. A major criticism of the NTPR program in a report issued by the National Research Council in 2003 was the lack of well-documented procedures and quality control. This criticism relates to both the dose reconstruction procedures that are used and the mechanisms of communications with Veterans. Dr. Reimann brings to the Board knowledge of quality management for complex, interactive systems such as the dose reconstruction and claims adjudication program for Veterans. Dr. Reimann currently holds the Mayberry Chair of Excellence at Tennessee Technological University, College of Business.
