  • Biography

    Dr. Jincheng Du is a Professor and Associate Department Chair for Graduate Program in the Department of Materials Science and Engineering of University of North Texas, Denton, Texas. Dr. Du received his Ph.D. in Ceramics from New York State College of Ceramics at Alfred University in 2004. He subsequently worked as a postdoctoral fellow at Pacific Northwest National Laboratory (PNNL) and later as a research associate at University of Virginia. He joined the MSE Department of UNT as a faculty member in 2007 and currently serves as the Graduate Advisor and graduate program director of the same department. Dr. Du’s research expertise lies in atomistic computer simulations of glass, ceramics, and nanostructured materials. He develops empirical potentials and computational tools to study glass, amorphous and nanostructured materials to understand their structure, surfaces, and interfaces. His current research topics include composition-structure-property relations of bioactive glasses, glass for nuclear waste immobilization, glass-water interactions and corrosion behaviors, glass-crystal interfaces and defects in ceramics and nanostructured materials. He is the Chair of Technical Committee on atomistic simulation and modeling of glasses of International Commission of Glass (ICG). Dr. Du’s research has been funded by NSF, DOE, AFRL, ARL, SRC and industry (with over $5M total external funding). He has published over 160 peer reviewed papers and proceeding papers. He recently co-authored a book on Molecular dynamics simulations of amorphous materials in the Springer Series of Material Science in 2015. Dr. Du is a frequent speaker on the topic in national and international conferences and has made over 70 invited talks and seminars. Dr. Du is the recipient of Early Career Award of Research and Creativity of UNT, Faculty Research Award of the College of Engineering , and Research Leadership Award of UNT . He is also the receipient of the Fulbright US Scholar Award and W.E.S. Turner Award of International Commission on Glass.

    Research Interests

    In FGM2L, we integrate atomistic computer simulations and materials characterization to investigate complex structures of materials, structural origin of properties with a focus on glass and glass-ceramic materials for energy, biomedicine, microelectronics, and environmental applications. Students are trained with both simulation and experimental skills to work on challenging scientific and engineering problems on federally or industrially funded projects. We welcome motivated students at all levels to perform high impact materials researches. The main research areas are summarized below:

     

    Atomistic computer simulations of material behaviors

    • Potential development for atomistic simulations of glass and ceramics Interatomic potentials are critical to atomistic simulations of materials. Our group develop interatomic potentials for silicate, borosilicate, and phosphosilicate glasses, as well as reactive potentials to study glass-water interactions, through empirical fitting and QM calculations.

    • Glass structure and structure-property relations Glass materials have many unique properties such as optical, dielectric, mechanical and others but the structure of glass lacks long range order hence defies any single experimental characterizations. We utilize both classical and ab initio based materials simulations to study the complex glass structures and structure-property relations of glass materials.

    • Simulations of glass corrosion and glass-environment interactions

    Glass corrosion and glass–environment interactions play an important role from glass processing, packaging, to glasses for biomedical and nuclear waste disposal applications. MD simulations with reactive potentials and MC simulations were used to understand the corrosion mechanisms in glass materials.
