Isotope geochemist trained in experimental, computational, and microanalysis techniques with applications to planetary chemistry and geology. Significant experience manipulating and analyzing small quantities of rare geological and spacecraft material samples. Programmatic skills include mission concept development, mission proposal writing and delivery, and the development of flight instruments for in situ chemical analysis (particularly mass spectrometry and laser spectroscopy).MISSION EXPERIENCESample Analysis Phase Participating Scientist Co-I, OSIRIS RExScience Co-I and Deputy VTLS instrument lead, DAVINCI Affiliate, SAM instrument team, Curiosity (MSL)Collaborator, GenesisSPECIALTIESAnalytical: Orbitrap mass spectrometry (GC-MS/MS); gas-source isotope ratio MS; secondary ion mass spectrometry (NanoSIMS 50L; SIMS 7f GEO); electron microprobe analysis; TIMS; GC-MS; ICP-OES; ICP-MS; RGA-MS; FE-SEM (imaging, EDS, EBSD, cathodoluminescence); FTIR spectroscopy (including ATR); Raman spectroscopy; UV-vis spectroscopy; NMR spectroscopy; XRD; XRF; TGA; NMR; XPS [limited]; petrographic and binocular microscopy.Laboratory: clean lab proficiency (including ion-separation column chemistry); solid-state materials synthesis and reactions; solution-based reactions and preparation / wet chemistry; organic and organometallic compound synthesis and separation; low-temperature, aqueous-based mineral syntheses; high-temperature, low-pressure mineral syntheses (1-atm, Lindbergh furnaces); high-temperature, high-pressure mineral syntheses (piston cylinder apparati); Karl Fischer titration (operated within Ar-purged glove box); gas-phase reactions / vacuum line construction and operation; laser fluorination of mineral separates for O-isotope analyses; mineral separation from whole-rock samples and micro-sample preparation and mounting; use of slab, trim, and lapidary saws for rock cutting; jaw crushers, mullite grinders, and shatterboxes for rock crushing; arc-welding, machining (lathes), use of drill and hydraulic presses, autoclaves, and laminar flow hoods; limited experience with DNA amplification and expression using PCR as well as microbiological and plant-tissue culturing.Computational: MATLAB, Visual BASIC; elementary UNIX, LAMMPS & Moldy (molecular dynamics), GAUSSIAN (DFT), Avogadro, ArcGIS, and MELTS (petrologic thermodynamic modelling).
