  1. NIH 2R01 DE017925
    PI. Yu Zhang
    Title: Graded Zirconia Structures for Resistance to Chipping, Delamination, and Fatigue
    Role: Principal Investigator

    The major goal of this competitive renewal proposal aims to further develop zirconia glass graded structures for next-generation all-ceramic dental restorations with improved resistance to chipping, delamination and flexural fracture, as well as improved cementation properties and aesthetics.

  2. NSF DMS-1436591
    PI. Robert Kohn
    Title: Adaptive Fine-Scale Structure Design: From Theory to Fabrication
    Role: Co-Investigator

    The principal goal of the proposed project is to build a bridge between advanced mathematical theory of microstructures, practical computational techniques, and experiment. The outcomes will include parametric families of microstructures, validated with computation, fabrication and experiment, and techniques for using these to solve specific shape optimization problems.


  1. NIH 2R01 AR056208
    PI. Yu Zhang
    Title: Biomaterials (MZF-CaP) for Osteoporosis Prevention, Therapy and Bone Repair
    Role: Principal Investigator (from 01/20/2013)

    The major goal of this project is to develop a safe, affordable calcium phosphate-based compound (MZF-CaP) that will be effective in preventing or recovering bone loss induced by disease (e.g. osteoporosis), therapy (e.g., radiation, steroid) or condition (immobilization, aging).

  2. NSF CMMI-0758530
    PI. Yu Zhang
    Title: Fatigue Behavior of Functionally Graded CeramicsÂľSynthesis, Experiments, and Analysis
    Role: Principal Investigator

    The major goal of this project is to establish the structure-property relationships of functionally graded materials by investigating their fatigue contact, sliding, and flexural damage resistance using a model glass/alumina/glass system.

  3. NIH 1R01 DE017925
    PI. Yu Zhang
    Title: Graded Structures for Damage Resistant All-Ceramic Restorations
    Role: Principal Investigator

    The major goal of this project is to develop an aesthetic, strong, and easy-to-cement zirconia based functionally graded material for less invasive all-ceramic posterior crowns and bridges, foreshadowing possibilities for orthopedic and other engineering applications.

  4. NIH 1R43 AR056167
    PI. Kenneth L. Lambert
    Title: Calcium Phosphate Bone Cement Nanocomposites
    Role: Consultant

    The objective of this project is to develop novel bone cement nanocomposites containing super-strong hydroxyapatite nanofibers. It is hoped that the novel calcium phosphate cement nanocomposites will have excellent biocompatibility and sufficient mechanical properties as a bone implant materials for many orthopedic applications, such as general bone grafts, prosthesis fixation, plateau fracture fixation, vertebroplasty, kyphoplasty, etc.
