Research Summary

Professor Liu’s research interests focus on the modeling and design of a wide range of materials chemistry and processing through integrating first-principles calculations, statistic mechanics, thermodynamic/kinetic modeling, and critically designed experiments for structural and functional applications.

Recent studies in Professor Liu’s Phases Research Lab concentrate on aluminum alloys, magnesium alloys, Ni-base superalloys, ion transport membranes, and ferroelectrics. The primary emphasis is on fundamentals of phase stability, defect chemistry, and their applications in understanding and predicting relationships among materials chemistry, processing, and properties.

Technology impacted by Professor Liu's research includes: lightweight materials for vehicle applications; solid-oxide fuel cells; Li-ion battery; solar materials; ferroelectrics, ionic transportation membranes, thermal and environmental barrier coatings; land-based and airborne gas turbine systems; and computational methodology in materials research and development transferable across inorganic materials.
