Research Interests

My research focuses on powder engineering and metal additive manufacturing of advanced materials for high-performance applications. I develop customized metallic powders, oxide-dispersion-strengthened alloys, metal matrix composites, and additively manufactured components with improved printability, mechanical performance, oxidation resistance, and reliability.

My broader interests include powder surface modification, nanoparticle-enhanced feedstocks, laser powder bed fusion, directed energy deposition, sustainable powder reuse, biomedical scaffolds, and AI/simulation-guided manufacturing. The long-term goal of my research is to connect powder design, additive manufacturing, microstructure control, and material performance for aerospace, energy, nuclear, biomedical, and next-generation manufacturing applications.

Research Highlights

Patent-Pending Powder Processing for AM and HIP
Developed patent-pending powder processing strategies to produce AM- and HIP-ready spherical metal powders with reduced surface satellites and decreased internal porosity, improving powder quality for advanced manufacturing applications.
Patent-Pending Processing of Spherical ODS Alloy and Metal Matrix Composite Powders
Developed patent-pending approaches for producing spherical oxide-dispersion-strengthened alloy and metal matrix composite powders for metal additive manufacturing, enabling the integration of nanoscale reinforcements into printable metallic feedstocks.
Additive Manufacturing Process Optimization for ODS Alloys
Optimized additive manufacturing processing conditions for ODS alloys to refine oxide/nanoparticle dispersions, improve microstructural uniformity, and enhance mechanical and high-temperature performance.
