Dennis D. Leber (Fed)

Mathematical Statistician

Prior to joining NIST's Statistical Engineering Division in January 2002, Dennis spent five years performing risk analysis and program development in the Actuarial Research Department at the Prudential Property and Casualty Insurance Company in Holmdel, NJ. Dennis received his B.S. degree in Mathematics from Bloomsburg University in 1997, a M.S. degree in Statistics from Rutgers University in 1999, and a M.S. degree (2007) and Ph.D. degree (2016) in Mechanical Engineering from the University of Maryland. His current research interests include experiment design to support selection decisions and multiple attribute decision making when faced with uncertain attribute values.

In his collaborative role in NIST's Statistical Engineering Division, Dennis provides leadership and guidance in problem formulation, experiment design, and statistical analysis for physical science research to the scientists and engineers at NIST and other Federal agencies. Over the past 10 years, Dennis has been a major contributor and key collaborator of scientific and technical staff of NIST's Ionizing Radiation Physics Division, and the Domestic Nuclear Detection Office of the U.S. Department of Homeland Security, in the design of radiation detection experiments and in the modeling and analysis of the resulting data. Other ongoing collaborations, with researchers in NIST's Office of Law Enforcement Standards (OLES), include studies of performance of ballistic body armor, and the advancement of measurement science for imaging equipment used by firefighters and other emergency personnel.

Dennis currently serves on the Board of Directors of the NIST Child Care Center in the role of Treasurer. In his personal time, Dennis enjoys participating in and watching his children's sporting events, bicycle riding and snowboarding, and beach time with his family.
