Additive powder and machine development for 3D printed parts.

Learned the Czochralski process for large diameter ingot growth.Led a business critical project to develop a new intermediate diameter crystal process and transfer it to operations.Implemented DOE techniques to test process windows, growth effects, and crucible material properties relevant to the process.

Performing research with ceramic materials. These duties primarily include material processing and structural characterization.Structural feature analysis by Raman SpectroscopySupervision and mentoring of undergraduate researchers

Developed, characterized, and improved a ceramic waste form (hollandite) for nuclear waste disposal applications (cesium immobilization)Characterization of hollandite by: X-ray diffraction (XRD), scanning electron microscopy (SEM), electron dispersive x-ray spectroscopy (EDX), and transmission electron microscopy (TEM)Other techniques utilized: infrared spectroscopy (IR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC)Major research projects:In-situ krypton irradiation (TEM), Argonne National Laboratory-Determined radiation tolerance of hollandite materials using Transmission electron microscopy (TEM)-Showed the material would exceed the stability requirements for waste form applicationsAqueous Leaching, Savannah River National Laboratory-Analysis of elemental dissolution dependence on material composition and propertiesXANES and EXAFS, SSRL, Stanford University-Characterization and analysis of local atomic structure for hollandite ceramicsDetermined high cesium loading leads to enhance stability of hollandite phase. Increased phase stability limited radiation damage and elemental leachingSecondary responsibilities:Supervised undergraduate researchers in their studies and projectsLab management for research group-material ordering-lab cleaning and safety
