Research Interests

I investigate how nanoscale compositional variations in alloys influence bulk properties. At Sandia, I (i) measure hydrogen isotope transport and trapping in metals; (ii) characterize advance materials with atom-probe tomography (APT); and (iii) manage materials data.

Research Experience

Senior Materials Scientist, Sandia National Laboratories — Livermore, CA — Apr 2010 – Present

  • Lead of W80–4 Materials@Risk (M@R) Task for Materials Compatibility Qualification and Database Lead for the multi-lab M@R initiative, where we’ve brought Granta Materials Intel-

    ligence into the Common Engineering Environment, integrated it with Windchill PDMLink, and created tools to assess and report on risk factors that may lead to materials unavailability.
  • Sandia Tritium Sustainment Manager, responsible for leading and conducting experiments for Tritium-Producing Burnable Absorber Rod (TP–BAR) program.
  • Principal Investigator of multiscale/multiphysics laboratory-directed research and develop-

    ment effort to predict and characterize environmentally-assisted intergranular fracture in Ni, where I also characterized segregation in grain-boundary engineered nickel using APT.
  • Measured thermal stability, deuterium permeation and deuterium trapping of additively-manufactured stainless steels to support multiple materials qualification efforts.
  • Measured deuterium permeation and trapping in Al–Cu alloys, candidate fusion materials,

    and candidate barrier materials.
  • Reported on the compositional variation and accelerated aging of hard Au(Co) coatings for

    electrical contacts.

Postdoctoral Scholar, Sandia National Laboratories — Livermore, CA — Oct 2007 – Apr 2010

  • Determined the fracture toughness and compressive behavior of ultra-fine-grained Al–Mg alloys and correlated these with observations from optical and electron microscopy.
  • Assisted in fabrication and calibration of a deuterium permeation instrument.
  • Measured the deuterium permeability through various Al–Mg alloys, 304L stainless steel, SiC (through Ultramet’s SBIR), Au-coated Be, and other materials.
  • Quantified Mg grain broundary segregation in nanocrystalline Al–Mg powders and consolidated, ultra-fine-grained alloys using atom-probe tomography (APT).

Ph.D. Candidate, Northwestern University — Evanston, IL — Sep 2002 – Oct 2007

  • Utilized APT and transmission elctron microscopy (TEM) to measure the composition and morphology of nanometer-scale precipitates in Al–Sc–RE (RE=Dy, Er, Y) and Al–Er.
  • Measured elevated temperature creep and the ambient temperature strength (yield stress and microhardness) of Al–Sc–RE alloys and oxide-dispersion-strengthened Al–Sc(–Zr).
  • Predicted mechanical performance using a novel dislocation creep model and by using APT reconstructions in dislocation dynamics simulations (DISLOC2D) of yield strength.
  • Developed software for APT data analysis (ENVELOPE (originally by M. K. Miller and J. Hyde), ELLIPSOIDFIT , INTERPPT , and others).
  • Helped maintain Northwestern University Center for Atom-Probe Tomography.
  • Co-lead developer of refbase, a free/open source web-based reference manager.

Research Assistant, California Institute of Technology — Pasadena, CA — Jan 2000 – Sep 2002

  • Programmed the SMARTS EXPERT SYSTEM to assist in neutron diffraction experiments.
  • Studied beam divergence of the SMARTS neutron diffractometer.
  • Assisted in collection and analysis of neutron diffraction data for residual stresses.

Research Assistant, LIGO — Hanford, WA — Jun 1999 – Sep 1999

  • Formulated optimal epoxy bonding techniques to couple magnets and standoffs to test masses used in the high vacuum Laser Interferometer Gravitational Wave Observatories.
