Dennis D. Leber (Fed)

Supervisory Mathematical Statistician

Dennis Leber is a Mathematical Statistician at the National Institute of Standards and Technology (NIST) in the Statistical Engineering Division (SED). Dennis serves as the leader of the Statistical Design, Analysis, and Modeling Group within SED.

Prior to joining SED 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 earned his B.S. degree in Mathematics from Bloomsburg University (1997), an M.S. degree in Statistics from Rutgers University (1999), and an 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 to the scientists and engineers at NIST and other Federal agencies in problem formulation, experiment design, and statistical analysis for physical science research. Throughout his career, Dennis has been a major contributor and key collaborator to many scientific and technical staff. Several notable and long-term collaborations include his work with 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; work with researchers in NIST's Office of Law Enforcement Standards (OLES) to study the performance of ballistic body armor and improve national body armor standards; and more recently, uniting with analytical chemists in NIST’s Materials Measurement Science Division to model the illicit drug landscape in efforts to combat the U.S. opioid crisis.

When he and his wife are not attending school and club sporting events for their two teenaged boys, you’ll find Dennis hiking local trails with his dog, cycling the rolling country roads of Western Howard County, or lost in the backcountry of the Rocky Mountains on his snowboard.
