About The Position

Conduct advanced atmospheric chemistry research focused on the measurement of water vapor and related trace species using Broadband Cavity-Enhanced Absorption Spectroscopy (BBCEAS) and Cavity-Enhanced Laser Frequency Modulation Spectroscopy (CE-LFMS) both in the visible and IR wavelength ranges. Responsibilities include building, calibrating, troubleshooting and operating this instrumentation as well as processing and analyzing high-resolution spectral datasets, developing and applying fitting routines for absorption cross-sections and concentration retrievals, and maintaining quality assurance protocols for field and laboratory measurements. Additional duties include conducting ozone-specific studies in Utah by applying modified forms of the Leighton relationship to investigate radical-driven photochemical processes, with particular emphasis on peroxy radical chemistry, NOx–VOC interactions, and deviations from photostationary-state behavior. This work will also involve integrating observational datasets with meteorological and radiation measurements, interpreting seasonal and diurnal ozone formation trends, and preparing technical reports, figures, and manuscripts for publication.

Requirements

• PhD in Analytical or Physical Chemistry. The required degree must be completed by the start date.
• Specialized expertise in atmospheric chemistry, photochemical ozone formation, and advanced optical spectroscopy.
• Extensive experience using BBCEAS for the measurement of trace atmospheric species and developing concentration retrieval methods from cavity-enhanced spectroscopic data.
• Proficient in MATLAB, Igor Pro, and atmospheric data analysis workflows for large spectral and environmental datasets.
• Experienced in preparing scientific publications, interpreting field observations from Utah air quality networks, and translating complex atmospheric measurements into meaningful conclusions regarding regional air quality and oxidation chemistry.
• This position requires the successful candidate to relocate and/or reside in Utah for the duration of their employment.

Nice To Haves

• Strong background in CE-LFMS, spectral fitting, absorption cross-section development, and instrumental calibration preferred.
• Demonstrated expertise in ozone photochemistry, including application of the Leighton relationship to diagnose radical chemistry and identify the role of peroxy radicals, NOx, and VOCs in ozone production.
