Dustin Poppendieck is an environmental engineer at the National Institute of Standards and Technology (NIST). He received his PhD in Civil and Environmental Engineering from the University of Texas at Austin in 2002. He is a fellow of the International Society for Indoor Air Quality and Climate (ISIAQ). Dustin has been investigating indoor air chemistry since 2002. Most of his efforts have involved characterizing primary emission sources and heterogeneous reactions at material surfaces. He has investigated emissions from kerosene can lamps used by nearly a billion people throughout the developing world, spray polyurethane foam, non-smoldering cigarette butts and indoor air cleaning devices. In addition, Dustin has studied the disinfection of biologically contaminated building materials (i.e., anthrax) using high concentrations of ozone, chlorine dioxide, hydrogen peroxide and methyl bromide. Recently, Dustin has been involved in writing and revising standards related to chemistry of portable air cleaners, including ASTM D8625, UL867, ASHRAE 241 and ASHRAE 145.4.
