Join Our Group

The Atmospheric Trace Molecule Spectroscopy Lab is always seeking talented, motivated students and postdocs to help improve our understanding of the atmosphere.

The ATMOSpec Lab applies a combination of instrument development and modeling to a variety of field and laboratory studies to better understand atmospheric chemistry with particular focus on the free troposphere and the marine boundary layer. We build unique instrumentation that is deployed on aircraft, ship, and ground-based platforms to measure trace gas molecules including glyoxal, halogen oxides, and NO2 to study e.g. radical cycling, mercury oxidation, and marine volatile organic carbon precursors. Additionally, we do chamber studies where recent projects have focused on the isoprene oxidation mechanism and secondary organic aerosol formation from multiphase chemistry. We use modeling to explore the depth of our understanding of these processes and then incorporate field and chamber data to improve model capabilities.

We have ongoing collaborations with other research groups within CU, scientists at NCAR and NOAA in Boulder as well as scientists at other American and international institutions including the University of Alabama Huntsville, the Paul Scherrer Institut in Switzerland, IRCELYON in France, University of Mainz in Germany, the University of Toronto in Canada, and the Hong Kong University of Science and Technology in Hong Kong.

Application Information


The Department of Chemistry at the University of Colorado generally only accepts students to the PhD program. Applications, including the general and chemistry GREs, are due in mid-December. Exact deadlines, additional application information, and forms can be found here: Prospective Graduate Student Admissions

We require an undergraduate background in engineering, physics or the physical sciences

Visiting the ATMOSpec Lab


If you are interested in joining our group, you are welcome to attend group meetings or stop by for a tour of the lab. Group meetings are currently on Thursdays from 2-4 pm in the CIRES reading room.
