Research interests
Chemometrics/Data Science
- Developing chemometric and data science tools to allow non data scientists to fully leverage their data.
- Develop techniques to combine information from multiple data streams to better understand a process, experiment, or system.
Materials Aging and Compatibility
- Using gas analysis techniques, such as Sector Mass Spectrometry, Gas Chromatography/Mass Spectrometry, and Selected Ion Flow tube mass spectrometry, to analyze headspace gas samples and understand material outgassing and potential material incompatibilities.
Spectroscopy
- Developing sensor platforms for ruggedized and/or embedded applications
- Spatial Heterodyne Raman Spectroscopy
Current position(s)
- Stockpile Surveillance Program Lead
- Aging and Lifetimes Program PI
- Gas and Data Science SME
Career path
2017 - 2019: Post Doc at LLNL doing Spatial Heterodyne Raman Spectroscopy (SHRS) for sensor development, Cyro GC/MS headspace gas analysis for materials compatibility, and various data science projects develop analysis tool or predictive models.
