Research

research overview

  • Dr. Ziemann's research focuses on experimental studies of the atmospheric and indoor air chemistry of organic gases and particles that affect human health, visibility, and climate. Laboratory experiments are conducted under simulated atmospheric conditions to elucidate mechanisms by which volatile organic compounds emitted from anthropogenic and biogenic sources react with oxidants to form products, some of which can condense to form microscopic particles. Information on the chemical composition of the products are used to develop atmospheric reaction mechanisms and models. These studies improve our understanding of atmospheric chemistry and aid in the development of air quality models for predicting the environmental fate of organic compounds and the formation and properties of organic aerosol particles and the impact of human activities on the atmospheric environment. Related studies focus on measuring and modeling the sources and fate of organic chemicals in indoor air.

Teaching

courses taught

  • CHEM 4141 - Environmental Water and Soil Chemistry
    Primary Instructor - Spring 2018 / Spring 2019
    Application of basic chemical principles to understanding the processes that determine the chemical composition of oceans, lakes, rivers, soils and sediments. Topics include air-water exchange; acid-base, redox, coordination, precipitation and dissolution, ion exchange and sorption reactions; nutrient chemistry; and the use of simple equilibrium and kinetic models for describing the chemistry of inorganic and organic species in air-water-soil systems. Same as CHEM 5141.
