    "summary": "Materials science expert and tenured Professor at Virginia Tech with deep expertise in solid-state additive manufacturing, metal matrix composites, dynamic microstructure evolution, and advanced materials synthesis. Ph.D. in Materials Science and Engineering from MIT with postdoctoral training under leading researchers in shape-memory materials and materials design. Proven ability to articulate complex technical concepts with precision — essential for evaluating the boundary between safe and unsafe requests involving materials science. Research spans process control, hybrid materials design, large-scale repair and cladding, and materials recycling. Editor for Materialia (Acta Materialia family). Strong foundation for authoring and reviewing AI safety evaluation tasks that require rigorous domain reasoning about materials behavior, processing risks, and dual-use implications.",
