    Small molecules in the Anthropocene: Oceans, Wildfires, and New Particle Formation from Iodine
    Rainer Volkamer, ANYL faculty, CU Boulder
    "The Volkamer group develops advanced optical instrumentation (in situ and remote sensing) to measure small molecules and aerosols that are relevant to public health discussions and climate. We seek to better quantify and understand emissions of small molecules, total carbon, and aerosols from natural and managed ecosystem (e.g., wildfires, oil & natural gas, ocean surface, UTLS), and develop a molecular level understanding of the fundamental processes that affect their chemical transformations and sinks (e.g., new particle formation). The combination of optical spectroscopy and high-resolution mass spectrometry is an emerging future theme in the group. Opportunities for graduate research exist in the areas of 1) field measurements using research aircraft (i.e., TI3GER-2022, CUPiDS-2023 projects), 2) laboratory experiments of particle formation (incl. at CLOUD/CERN) and multiphase chemistry, and 3) instrumentation to study carbon closure, and exploit synergies between optical spectroscopy and mass spectrometry."
    and
    Atmospheric chemistry of reduced nitrogen and organosilicon
    Eleanor Browne, ANYL faculty, CU Boulder
    "The Browne group uses a combination of laboratory experiments and field measurements to understand the sources and transformations of trace gases in the atmosphere with the ultimate goal of understanding the impacts of this chemistry on air quality, climate, and nutrient delivery to ecosystems. Here, I will discuss some of our recent work on the atmospheric chemistry of cyclic volatile methyl siloxanes and of reduced nitrogen compounds. Finally, I will discuss research opportunities in our group."
