Senior Staff Scientist
Environmental Molecular Sciences Laboratory,
Pacific Northwest National Laboratory
January 2024 - Present [Scientist IV]
July 2020 - December 2023 [Scientist III]
I am Principal Investigator on several science and technology development projects,
including research on advanced instrumentation, methods, and deep learning informed
data processing. I lead a significant, multi-year project to develop and upgrade EMSL’s
flagship 21 Tesla FT-ICR mass spectrometer, with tasks including hardware and software
development, scientific research, and project management. I couple novel ionization
sources and electronics to FTMS instrumentation, develop new methods for NMR and
MS analysis for complex organic mixtures, lead efforts to improve sample preparation,
laboratory automation, AI-informed automatic instrument optimization, and co-develop
sophisticated new data processing software, including CoreMS.
I also support a range of scientific investigations with both EMSL users and other scientists
at PNNL, using both MS and NMR. These include analysis of natural organic matter,
including soil, water, and aerosols, as well as research in metabolomics and proteomics.
Key topics include understanding effects of fire or drought on soil chemistry, origin and
fate of biomass burning aerosols, mineral-organic matter interactions, as well as understanding
metabolic processes in complex systems and characterization of proteoforms
within biological tissues. Roles include experiment design, measurements, analysis, and
report writing. In this position, I also mentor and support junior scientists.
