• Performed landscape analysis on data-related activities in AM to identify high-priority research topics as well as potential future collaborators.
• Authored white-papers to provide better awareness to the AM community of the R&D projects that are currently on-going at the ASTM International AM CoE.

Park City, UT

• Tuned thermal solver parameters using Python ML libraries to improve the accuracy of a metal powder-bed fusion (PBF) simulation software. Decreased error in simulation by more than 50%.
• Built a data visualization tool to automate the identification of the optimal process parameters (laser power, scan speed) for metal PBF process based off user-defined mechanical properties (porosity, grain size, melt.

Park City, Utah

• Performed multi-variate analysis on a porosity and distortion DOE to determine the influence of build parameters and solver choice on simulation accuracy.
• Processed CMM and point cloud data to eliminate surface roughness and determine the physical distortion of parts built using metal PBF.

Austin, Texas Area

• Designed support strategies and analyzed parts in order to assess manufacturability to achieve first-time build success. Set-up builds collectively worth $200k in components.
• Developed a statistical process control (SPC) application in Python that employed six sigma principles for process monitoring.

Bryan/College Station, Texas Area

• First author on literature review on nickel-based superalloys as applied to additive manufacturing technologies including: powder-bed fusion, direct energy deposition, and binder jetting.

Austin, Texas

• Designed experiment to identify the mechanical testing technique most sensitive to manufacturing defects.
• Developed QC work instruction and MATLAB script used to calculate the minimum acceptance criteria (design allowables) of mechanical properties.
• Designed experiment to investigate the effects of thermal degradation on the recyclability of a carbon fiber powder using material characterization methods.
