Boulder, Colorado, United States
Expert in analytical chemistry, ultraviolet-visible optical remote sensing, and mass spectrometry. Experienced developer in IGOR Pro, Python, and LabVIEW.
Established a statewide air toxics monitoring network of cavity ringdown optical spectroscopy instruments. Developed, maintained, & operated two mobile laboratory platforms, each equipped with a Proton-Transfer-Reaction Time-of-Flight Mass Spectrometer (PTR-ToF-MS), a Chemical Ionization Time-of-Flight Mass Spectrometer (CI-ToF-MS), a cavity ringdown spectroscopy instrument, and a meteorological station. Developed software in IGOR Pro to analyze air toxics data from stationary and mobile platforms. Prepared public air toxics monitoring reports detailing measurements utilizing optical spectroscopy and mass spectrometry. Publicly presented air toxics monitoring data.
Designed, built, installed, and operated ultraviolet-visible Multi-AXis Differential Optical Absorption Spectroscopy (MAX-DOAS) remote sensing instruments at four long-term measurement sites: (1) Mauna Loa Observatory, Hawaii; (2) Maido Observatory, Reunion Island; (3) Storm Peak Laboratory, Steamboat Springs, CO; (4) Utah State Correctional Facility, Salt Lake City, UT. Installed and operated an airborne MAX-DOAS instrument on three different research aircraft (University of Wyoming King Air, NOAA Twin Otter, NSF Gulfstream V) for multi-week scientific field campaigns. Developed software in IGOR Pro to analyze spectral remote sensing data, interface with a 3D Monte Carlo radiative transfer model, and ingest global chemical transport model output (GEOS-Chem, WACCM, ECMWF CAMS). Developed LabVIEW software to test and control scientific instrument hardware for ultraviolet-visible & infrared optical remote sensing. Presented scientific results at domestic (AGU, AMS) and international conferences & workshops (Italy, Belgium). Authored or co-authored twelve peer-reviewed publications, including high-impact papers in Nature Chemistry & Nature Geoscience. Mentored four junior colleagues to operate spectroscopic remote sensing instruments and analyze remote sensing data.
Used vacuum apparatus, cryogenic systems, and a gas chromatograph-mass spectrometer (GC-MS) to quantify trace gas concentrations inside firn air flask samples and ice core air bubbles from Greenland and Antarctica. Developed code in Python to analyze & visualize GC-MS data. Wrote an undergraduate thesis providing evidence for the in-situ production of methyl chloride, methyl bromide, and carbon disulfide in glaciers and the resulting bias in the paleoclimatological record.
Developed and tested a miniaturized gas chromatograph and quadrupole ion trap mass spectrometer for deployment onboard the International Space Station and Orion manned missions. Constructed vacuum apparatus and performed leak testing on the gas chromatograph chassis.
