Summary

Jason T. Sebastian, Ph.D. is the manager of QuesTek’s “Technology Group” (which, as of September 2015, includes 11 full-time employees—10 with Ph.D. degrees, and 1 with an M.S. degree).  He is a specialist in the fields of computational materials design and nanostructural materials characterization. Since joining QuesTek in 2006, his work has focused on: the development of high strength steels for structural and power transmission applications; precipitation-strengthened Co-based alloys; alloys for additive manufacturing; non-toxic, high-strength/low-friction Cu-based alloys to replace Pb-containing bronzes; a low-cost, castable titanium alloy; a highly-processable Ni-based superalloy; advanced soft magnetic alloys; and other computationally-designed alloys. His past research activities include extensive experience with advanced characterization techniques including electron microscopy and atom-probe tomography.
