George Mulholland (Assoc)

Dr. George W. Mulholland is a guest researcher in the Fire Measurements Group of the Fire Research Division (FRD) of the Engineering Laboratory (EL) at the National Institute of Standards and Technology (NIST). Dr. Mulholland devoted much of his 32 years at NIST to the study of smoke and aerosol phenomena. His particle-related research included the study of the growth and properties of smoke agglomerates, characterizing the smoke produced from large-scale fires, and the development of primary standard calibration particles. He has also been active in a project to characterize the effect of combustion conditions on carbon monoxide and smoke production from fires.

Dr. Mulholland has published more than 100 papers, a chapter in the Society of Fire Protection Engineers Handbook on Smoke, and co-edited a symposium volume for the Journal of Atmospheric Environment entitled "The Global Climatic Effect of Atmospheric Aerosols." He led the development of primary standard calibration particles with diameter of 0.1 and 1.0 mm and assisted in the development of a smoke detector tester. Dr. Mulholland received the Department of Commerce Bronze Medal in 1985 for smoke research and in 2004 for nanoparticle sizing metrology.

Dr. Mulholland is a member of the American Chemical Society, the American Physical Society, the American Association of Aerosol Research.  He was a Visiting Professor at Tokyo Science University in 1980, Visiting Scientist at the Particle Technology Laboratory at the University of Minnesota in 1976 and 1989, at the Fire Research Institute of Japan  in 1988, 1989, and 1990, and at the Particulate Materials Center at the Pennsylvania State University in 1991-1992.
