Biography
Jennie is a postdoctoral researcher at Lawrence Livermore National Lab where she works on alloy development via additive manufacturing of gradient materials for high-throughput microstructure characterization and analysis. Her graduate research focused primarily on developing aluminum alloys that can maintain high strength during long times at elevated temperatures (300-400 °C). After her PhD, she worked as a postdoc on fabricating and quantifying bespoke refractory alloy powders via electrode induction melting inert gas atomization (EIGA). At LLNL, her focus is on the processing and evaluation of titanium-based and refractory (Ta, Nb, Mo, W) alloy systems via directed energy deposition (DED).
